Multiplying Integers
Skill Practice!
Find each product. Example: -3 (4) = -12 3 (4) = 12
1.) –5(20) 2.) 16(–2) 3.) 6(0)(–2) 4.) –9(8)(1) 5.) –1(–1)(–1)
6.) 12(10)(5) 7.)–50(–21)(2) 8.) –8(–13)(–25) 9.) –9(-8)(2) 10.) –5(16)(4)
ALGEBRA Simplify each expression. 8a(–5b) = (8)(a)(–5)(b) = (8 –5)(a b) = –40ab
11.) –2 3x 12.) 4r (7s) 13.) (–3)(4)(–x)
ALGEBRA Evaluate each expression if x = -5 and y = -6.
Evaluate –3xy if x = –4 and y = 9 –3xy = –3(–4)(9) = [–3(–4)](9) = 12(9) = 108
14.) . –xy 15.) . –6xy
