How is the number of digits determined for an answer obtained by adding or subtracting?
The number of digits in the result of an addition or subtraction operation is determined by the number of decimal places in the numbers being combined. The answer should be rounded to the least number of decimal places present in any of the numbers involved in the operation. For example, if one number has two decimal places and another has three, the result should be rounded to two decimal places. This rule ensures that the precision of the result reflects the precision of the least precise measurement.

How many significant figures should be in the answer obtained by adding 0.04 31.2 and 100.0?
The answer is limited to the number with the fewest digits of precision (digits after the decimal point). (2 digits of precision)
Why is it important to line up the decimal points when adding or subtracting but not when multiplying?
Because when adding or subtracting, the operations must take account of the place values of individual digits in the numbers. When multiplying, only the overall order of magnitudes are relevant for placing the decimal point in the product.
When adding or subtracting decimal how can you be sure to add or subtract only digits that have the same place value?
The simplest way is to line up the numbers so that their decimal points are aligned, and corresponding digits are also aligned according to their place value.

How do you do subtracting fractions with regrouping?
You do by subtracting one from the previous number and adding 10 to the top number of the digits you are regrouping. Subtract those two digits and you should get your answer.

When adding and subtracting decimalshow can you be sure to add or subtract only digits that have the same place value?
You line the number up, vertically, so that the decimal points are one below the other.
How do you get 154 using 66334?
To obtain 154 from the digits in 66334, you can perform the operation 66 - 33 + 4 = 154. By subtracting 33 from 66 and then adding 4, you arrive at the desired result of 154.
