Chapter 2: Adding Integers Objective: Learn to add integers.
Rules for Adding Integers with the Same Sign: 1. When Adding integers with the same sign, you just have to add both numbers. If both numbers are positive, the answer is positive. If both numbers are negative, the answer is negative. Example 1: 7 + 4 = 11 Example 2: -7 + (-4) = -11 Your Example: -26 + (-17) = __________ Your Example: 5 + 7 = ___________
When adding Integers with different signs: When adding integers with different signs, you must subtract both numbers. The answer will take the sign of the larger absolute value (number.) Example 1: 7 + (-1) = 6 Example 2: -8 + 3 = -5 Your Example: 10 + (-12) = _______ Your Example: - 3 + 8 = _________
To Summarize: When Adding Integers : + + + = add (+) - + - = add ( - ) - + + + + - Subtract! The answer takes the sign of the larger number.
Practice Exercises: Solve, follow the adding integers rules.
