Math Problem Statement
Solution
The image presents two addition problems with integers. Let me solve them for you:
-
The first expression is: When adding two negative numbers, we add their absolute values and keep the negative sign: So, the result is:
-
The second expression is: When adding a positive number and a negative number, we subtract the smaller absolute value from the larger one, keeping the sign of the larger absolute value: So, the result is:
