What happens when you add a positive number to a negative number?

• The result is always zero

• The result depends on the magnitude of the numbers

• The result is always negative

• The result is always positive

Why is 8 plus (-3) equal to 5?

• Because they are both negative

• Because negative numbers decrease the total

• Because they are both positive

• Because 8 is greater than 3
