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?
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.
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!
To subtract 0.5 from 0.05 first line up the decimal points in your equation. If you need to add a zero behind the 5 in 0.5 so you get 0.50. Then subtract as if there was no decimal point (take it as 50-5). After you subtract bring the decimal point down. You should end up with 0.45.

does how many mean add or subtract
explain why it is important to line up decimal numbers by their place value when you add or subtract them

Add, subtract, multiply and divide.

You can use decimal models to add decimals by using the hundedths blocks as used in base-ten blocks and add the following decimals you need to and use the hundredths block to shade in the total.
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.

I think it is 9!
(A) Add them together.(B) Subtract the smaller from the larger.

This is true for adding and subtracting ALL numbers, not just decimal representations.
