36 + (-28) + (-16) + 24 = y

Thank you

Numbers in parenthesis means the number is what it is. In the example, the number reads NEGATIVE sixteen. The - sign means negative, not minus. Reading the problem yields:

thirty-six plus a negative twenty-eight plus negative sixteen plus twenty-four.

when adding numbers, the elementary rule is to add like signed numbers

36+ 24 = 60

-28-16= - 44

Then subtract, taking the sign of the larger

60- 44= +16

This is the rule we learn in elementary school. Later, we learn we can go left to right with the same process

36 + (-28) + (-16) + 24

36 + (-28)=8

8 -16= -8

-8+ 24= +16
