Applying Addition and Subtraction of Integers Lesson 1.4

We are going to simplify problems that have both addition and subtraction Introduction Like this one: – 8 – (-4) Notice: The addition stays the same The subtraction needs to be turned into addition using KFC

Underline the numbers that can stay the same. Circle the numbers that need to be changed. Remember to include the subtraction sign. KFC the circled numbers. Add all positive integers. Add all negative integers. Lastly, add integers. Strategy

Examples: A) – 8 – (-4) KFCFC (-8) (-10)

Examples: B) 5 – 8 – – (-7) KFCFC 5+ (-8) (-17) FC + (-9)

Examples: C) -7 – 3 – (-8) – 9 KFCFC -7+ (-3) (-19) 0 FC (-9)

Examples: D) 8 – 9 – (-11) – – KFCFC 8+ (-9)+ (-4) 31 +(-14) 17 FC (-1) FC
