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 .

# What are step for subtracting decimals?

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.
