Answer 1

Rule 1: To add two integers of unlike signs we find the difference between their values regardless of their signs and give the sign of the integer with a more numerical value.

Rule 2: If two integer of like signs is added, we add their values regardless of their signs and give the sum their common sign.

Here, using the rule for the addition of integers with unlike signs, we have :

$-349+37=-(349-37)$

$=-312$
