Subtracting Integers page 1.3 - 17 Section 1.3 Focus Exercises 1. Rewrite each subtraction as addition. Then, evaluate the sum. a) 10 3 = = b) 15 5 = = c) 8 – 12 = = d) 9 9 = = e) - 2 4 = = f) - 6 9 = = g) 3 8 = = h) - 16 1 = = 2. Use the Commutative Property to rewrite each of these. Then, evaluate the expression. 7 – 4 = = b) 2 12 = = - 3 + 6 = = d) - 9 1 = = - 10 8 = = f) 8 20 = = g) - 15 + 51 = = h) 22 29 = = 3. Rewrite each expression into words using and and the opposite of . Then, rewrite the expression as a sum and evaluate . 8 ( - 10) = = = b) - 3 ( - 4) = = = 7 – ( - 9) = = = d) - 9 ( - 4) = = = - 12 ( - 7) = = = f) - 6 ( - 6) = = = 4. Rewrite each subtraction as addition. Then, evaluate the sum. 2 – (- 7) = = b) 12 (- 2) = = - 3 (- 5) = = d) - 6 (- 7) = = - 4 (- 4) = = f) 0 (- 10)= =
