Why do you have to place a zero as a placeholder when adding subtracting decimals?
A zero placeholder is necessary when adding or subtracting decimals to ensure that numbers are aligned correctly according to their place values. For example, if you have 2.5 and 1.75, it helps to write 2.50 to clearly align the tenths and hundredths places. This alignment prevents errors in calculations by maintaining the proper value of each digit, allowing for accurate addition or subtraction. Without the placeholder, it could be easy to miscalculate by misaligning the digits.
When adding or subtracting decimals always do what?
First you write the decimals one under the other, in such as way that the decimal points are aligned.
