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!
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?
wich one
Place Value Charts help you because they put the decimal in the right place.
You write down the numbers you want to add and subtract, making sure the decimal points are aligned. Then, you add (or subtract) EXACTLY as you would add or subtract integers. The decimal point in the solution should be aligned with the decimal points in the original numbers.
add them or subtract them, as appropriate!

You subtract decimals together.
You line up the decimals and simply subtract. Below is an example. 2.989-1.989= 2.989 1.989 --------- 1.000
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.

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.
