Will your answer be positive or negative? Sort the expressions to either a positive answer or negative answer. Positive Answer 4 x 5 20 x 12 -14 x -10 -13 x -4 -22 ÷ -2 35 ÷ 7 -50 ÷ -10 12 ÷ 6 Negative Answer - 4 x 5 20 x -12 14 x -10 4 x -13 22 ÷ -2 -35 ÷ 7 50 ÷ -10 -12 ÷ 6 Can you multiply and divide? Pick the correct answer fro each expression. 4 x 5 = 20 20 x -12 = -240 14 x -10 = -140 -13 x -4 = 52 -35 ÷ 7 = -5 -22 ÷ -2 = 11 50 ÷ -25 = -2 -12 ÷ -6 = 2 -35 ÷ -7 5 -20 x -12 = 240 -4 x 5 = -20 14 x 10 = 140 -13 x 4 = -52
