Answer 1

Try using a number line. For the first problem....

start at -5 and count back(to the left) when adding another negative number.

For the last problem, start at -5 and count to the right (for a positive number), then from the number you arrived on, count back to the left for the -9.

When adding negative numbers count to the left.

When adding positive numbers count to the right.
