# Lesson 5 Adding and subtracting integers. **Remember** The sum of two positive integers is a positive integer. **Note:** A positive integer may or not have a positive (+) symbol written before its number. **Remember:** To add positive and a negative integer (vice-versa): Find the absolute value of each integer. Subtract the smaller number from the larger number. Then the sign of your final answer will be the sign copied from the integer with the larger absolute value. | Integer Sign | Answer Sign | Operation | Example | |---|---|---|---| | + + | + | add | 4 + 6 = 10 | | + - | - | subtract | 16 + (-7) = 9 | | - + | - | subtract | 5 + (-11) = -6 | | - - | - | add | (-3) + (-4) = -7 |
