Answer 17

This is how you add two numbers:
1. If both numbers are non-negative, just add them together like you've always been doing.
Examples: 2 + 5 = 7; 3 + 0 = 3; 21 + 22 = 43
2. If both numbers are negative, ignore the signs, add the numbers, then the answer is negative.
Examples: -4 + (-2) = -6; -32 + (-32) = -64
3. If one number is positive and one number is negative, ignore the negative sign, and subtract the smaller number from the larger number. Then the answer will have the same sign as the larger number.

Example 1:
-8 + 9
Subtract 9 - 8 = 1
SInce 9 is larger than 8 and 9 is positive, answer is positive, so
-8 + 9 =1

Example 2:
18 + (-23)
Subtract 23 - 18 = 5
Since 23 is bigger than 18, answer has same sign as -23, so
18 + (-23) = -5
