How are the expressions 8 - 15 and 8 +(15) alike? How are they different?

Well, one thing they ahve in common is that they are both adding or subtracting the same numbers and of course, they are both expressions.

They are different because one expression is subtract both numbers while one expression is adding both numbers.

8 + 15 = 23
