Question

Please help me!!! And explain why you would do that because i dont get it????

Answer 1

For the example you gave of m+83, you would just write it out, like "m plus eighty three"

Answer 2

It's teaching you how to interpret word problems by having you convert the expression to words you may see in a problem. This expression may be seen in a word problem as "the sum of a number and eighty three".
