align the decimals and subtract as you normally would. make sure after subtracting you bring the decimal down. replace empty space with zeros. for example: 1.340 - 1.3250 will look like this 1.340 - 1.3250 another example: 10.39485 - 9.847 will look like this. 10.39485 - 9.84700
Answer . the number that is being subracted (4-5) the 5 is called a subtrahend and the other is a minuend.
You line up the decimals and simply subtract. Below is an example. 2.989-1.989= 2.989 1.989 --------- 1.000
Adding and subtracting decimals is easy. When you put the numbers one above the other, line up the decimals vertically and treat as you would any whole number just keep the decimals in line and bring it straight down to your answer.
How To Add/Subtract Decimals . To add decimals you HAVE TO LINE UP THE DECIMAL POINTS and then add the numbers up (Tip: when your first starting if the decimals don't go to the same place value you can add as may zeros at the END of the decimal. This does NOT change the place value). Afte…r you have added up the digits you "drop" the decimal point down.. Example 105.43+23.4=? 105.43 +23.4 0 ----------- 128.83 . To subtract decimals it's the same thing as adding YOU MUST LINE UP THE DECIMALS. You would subtract as you normally would. . You would then "drop" down the decimal point. Example 109.783-43.39=? 109.783 -43.39 0 ---------- 66.393 (MORE)
regardless of what the problem is, they are always called integers. unless you have variables or fractions in the problem.
By doing this it aligns all the place values so you can clearly add or subtract the correct place values and get a correct answer. You might say it is an organization technique. Of course if you use a calculator, this is not necessary.
how do we add or subtract decimal?. its the same thing as using regular subraction and addition.. Example:. 12.4. +8.1. ______. =20.5. The same in subtraction! Just keep the decimals alligned!
The same way you'd add any other negative numbers. Adding a negative is the same as subtracting, and subtracting a negative is the same as adding. (-2) + (-2) = (-4) (-2) - (-2) = 0 you are wrong if you add or subtract two negitives its always a positive dont you know your math. And the second… problem you have is wrong to because when you subtract two negitives you change the sign of the secong number to positive and you change the subtraction sign to a addition sign.

-to add or subtract decimals, line up the decimal points -add or subtract the same way you do with whole numbers ex: 12.4 +8.1 ______ 20.5 You can also do this strategy: 2.0 +6.0 _____ 8.0
The traditional names for the parts of the formula . c â b = a . are minuend ( c ) â subtrahend ( b ) = difference ( a ). The words "minuend" and "subtrahend" are not used much now. The answer is still called the difference .
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. . 2.5 . -1.4 =1.1 . hope this helps and if not yahoo usually has good examples.
because if you don't know the place value you might have trouble answering the question and you might get it wrong .
well that's kinda hard. but for adding it is to count on. like for example 1+1= that's a good start. when you add 1+1 do you go upward or downward.upward is the answer.so1+1=2. subtraction is easy. now that you know how the adding goes.now let's start with the BASICs 8-8=.when you subtract 8-8 do yo…u go upward or downward. downward is the answer that means that 8-8=0.

Yes, When Adding and Subtracting decimals you should line up the decimals. You need to keep each place value in the same column, the same as when you add whole numbers you keep the ones column lined up, same for the tens, etc. Lining up the decimal points makes sure that the tenths column is kept to…gether, same for the hundredths, and so on.

You can do reverse operation to check. If you checked it and it is not the answer you got, try the problem and recheck it to see if your right.
By converting the actual fraction into a decimal for example 1/2 (one half) would become 0.5 0.25 (one quater) becomes 1/4 0.5 - 0.25 = 0.25 think of it as money 50p subtract 25p. Try going to school. They actually teach that stuff there. Sorry,I have just had a go at this and wiped… it off . It's to difficult to teach arithmetics or maths unless you are actually present.I suggest you follow our previous colleagues advice and enrol in a class somewhere. (MORE)
In any subtraction sum, such as 8 - 3 = 5, the first number is the minuend, the second number is the subtrahend, and the third number, following the equals sign, is the difference.
The minuend is the first number in the equation from which the subtrahend is subtracted. 12 - 7 = 5 ... 12 is the minuend, 7 is the subtrahend, 5 is the difference.
First you write the decimals one under the other, in such as way that the decimal points are aligned.
This happens when an answer to a problem that is a decimal is rounded in order to produce a meaningful answer?
You lose some accuracy in exchange for better understanding. If that is the only reason for rounding, then the unrounded version should be used for subsequent calculations.
You take the two numbers that are the smallest and add those together to see if the make the bigger number. If they do, good job, you got it right. If they don't check your math. By doing it in reverse. 96 - 35 = 61 because 61 + 35 = 96
When you are adding and subtracting decimals, youare +/- ing the whole numbers and tenths in the number. the decimal might go away ex: 1.3-0.3=1 or it won't ex: 1.9-0.3=1.6
You can either convert the decimal to a fraction and then subtract (3/4 - 0.5 = 3/4 - 2/4 = 1/4), OR you can convert the fraction to a decimal and then subtract (3/4 - 0.5 = 0.75 - 0.5 = 0.25).
you add and subtract decimals by writing down your number and then line up your decimal's.yourwelcome kinda smart for a math problem like that huh?
If you calculated x - y = z then calculate z + y. If the answer is x your calculation is fine. If not, one of the sums went wrong.
Its easy, dont worry about the decimal and do regular subtraction and at the end just add the decimal right under all the other decimals.
Subtract the smaller one from the bigger one, and then put a minus sign before the answer.
because you subtract the 2 numerators and then 2 denominators right across just like that :)
To add decimal numbers: . Put the numbers in a vertical column, aligning the decimal points . Add each column of digits, starting on the right and working left. If the sum of a column is more than ten, "carry" digits to the next column on the left. . Place the decimal point in the answer directly… below the decimal points in the terms. To subtract decimal numbers: . Put the numbers in a vertical column, aligning the decimal points. . Subtract each column, starting on the right and working left. If the digit being subtracted in a column is larger than the digit above it, "borrow" a digit from the next column to the left. . Place the decimal point in the answer directly below the decimal points in the terms. . Check your answer by adding the result to the number subtracted. The sum should equal the first number. (MORE)
When you have a negative number after the subtraction sign it turns in to addition. For example +7 - (-7) = 14 and (-7) - 7 = (-14)
school you can always get help from teachers, parents or people who think might know
Convert them to improper fractions, make sure the denominators are the same and fire away.
all you have to do is like say you have to figure out what's0.5-0.3 you have to subtract 3 from 5 and then you get the answer!it's easy! Put one number on top of the other, with the decimal points linedup. The one that you are subtracting from is on top. Then subtracteach column, starting with the …one on the right and working to theleft. You may have to borrow from the column to the left wheneverthe bottom number is bigger than the one above it. To borrow,subtract one from the column to the left, and add 10 to the columnyou are in. Example: 123.345 - 34.567 Line up one above the other with the decimal points lined up. 123.345 34.567 Subtract the column farthest to the right first. Notice that the 7is bigger than the 5; so make the 4 in the column just to the leftinto a 3, and add 10 to the 5 to make it 15. Now you can subtract 7from 15, which gives 8. 123.3315 34.567 ----------- 8 Now move one column to the left and subtract the next column.Notice that the 6 is bigger than the 3; so you will need to borrowagain. Make the 3 in the tenths column into a 2, and add 10 to the3 in the hundredths column, making it a 13. Subtracting the 6 from13 leaves 7. 123.2 13 15 34.5 6 7 ------------- 7 8 Now move one more column to the left. You are now in the tenthscolumn. Again the 5 is bigger than the 2, so you will have toborrow again. Make the 3 in the ones column into a 2 and make the 2in the tenths column into a 12. 122.12 13 15 34.5 6 7 ----------------- 7 7 8 Now bring down the decimal point, and start working on the onescolumn. The 2 is less than the 4; so borrow again. Make the 2 inthe tens column into a 1 and make the 2 in the ones column into a12. Subtract 4 from 12 to get 8. 11 12.12 13 15 3 4. 5 6 7 ----------------- 8. 7 7 8 Now move left one more column. 3 is less than 1; so borrow again.There is only 1 in the hundreds place; so take it, put a 0 in thehundreds place, and make the 1 in the tens place into an 11.Subtract 3 from 11 to get 8. 0 11 12.12 13 15 3 4. 5 6 7 -------------------- 8 8. 7 7 8 Since there is a zero in the hundreds place in the top number, andnothing in the hundreds place in the bottom number, you are alldone.

make it a '+ negative number'. Example: 6 - 7 = -1 6 + (-7) = -1
Using the vertical subtraction, make sure the numbers are written with the decimal points aligned. Put a decimal point in the answer immediately under the other two decimal points. If there are not enough digits after the decimal point in the top number, zeros can be appended (added to the rig…ht hand end) without changing its value. Now subtract the numbers like normal, the decimal point can be treated as a mark on the page during this. Read the answer, including the decimal point. Example: 51.8 - 2.96: __ 51.80 ___ 2.96 __------- __ 48.84 â 51.8 - 2.96 = 48.84 (MORE)
Line up the numbers in such a way that the decimal points are aligned. . Example: 567.89 - 23.4 567.89 - 23.4 = 544.49
It is difficult to answer the question because, for addition or subtraction, it is often easier to obtain the exact answer! If you line up the decimal points and then follow the rulesof addition or subtraction - exactly as they would apply to wholenumbers - you will get the correct answer! Estima…tion may be useful to check your answer if you are poor ataddition or subtraction of integers. But, if that is the case, yourestimate is equally likely to be wrong! (MORE)
There are infinitely many possible answers. Take any number N. Find M = N + 10 Then N - M will always be -10 For example, N = 3.75 then M = 3.75 + 10 = 13.75 and N - M = 3.75 - 13.75 = -10
They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.
For example: three hundred and forty five minus six hundred and forty two equals three hundred and three. thats how u write it in words
The same as integers without decimals. Just make sure the decimals are directly above and below one another. Use zeros as placeholders if you don't have enough numbers, that is, if one decimal is longer than the other.
Today was pay-day at the shop. It could not have come at a better time, as I was flat broke. I was paid my usual $243 after deductions. On my way home, I stopped at the big Green Wall pharmacy and monomart for supplies. Two prescriptions were ready, and as long as I was there anyway, I picked …up toothpaste, a notepad, a 30-foot extension cord, and this month's issues of QST, Scientific American, and Patriot Gunslinger. I paid cash at the checkout because Aruna was working the register and I love watching her try to make change. The total with tax came to $44. How much money did I have in my pocket when I got home ?

there is no limit as there is no limit for numbers,answer by Pranit Prabhu of Bangalore
It depends on the problem. An integer subtraction can be one number, take away another number.
Because if you don't line them up by the decimal, you could see a 9-3, when in fact it could be 9-30 or 90-3 accidentally. Mistakes happen. best to keep it simple
The key would be to add (00.) before your decimal. IE 00.41 + 00.95 = 01.36
1) Write the numbers one above the other with the decimal points aligned; 2) Write the decimal point in the answer directly under the decimal points in the numbers; 3) Now add/subtract the two numbers "ignoring" the decimal points as if they were whole numbers, but if there is a blank in one of …the numbers take it to be a zero. eg 12.34 + 45.6: 12.34 45.6_+ ------- 57.96 eg 12.3 + 5.64: 12.3_ _5.64 + ------ 17.96 eg 57.2 - 2.34: 57.2_ _2.34 - ------- 54.86 (MORE)
No, you don't move the decimal in subtraction. However, you mayneed to add trailing zeroes after the decimal in order to makesubtraction easier.
Add the result to the number you were subtracting; if this equalsthe original number then the subtraction is likely to be correct. example: if you calculated 123 - 56 and get the result 67, check byworking out 67 + 56 and see if you get 123.
