Which is greater? 5 + 7 × 10 or 5 + 7 × 10

Given, 5 + 7 × 10 or 5 + 7 × 10 Simplify given two equations and check the greatest. 5 + 7 × 10 = 12 × 10 = 120 5 + 7 × 10 = 5 + 70 = 75 We see, 120 > 75 Hence, 5 + 7 × 10 is greater.

Which is greater? 5 - 7 × 10 or 5 - 7 × 10

Given, 5 - 7 × 10 or 5 - 7 × 10 Simplify given two equations and check the greatest. 5 - 7 × 10 = - 2 × 10 = - 20 5 - 7 × 10 = 5 - 70 = - 65 We see, - 20 > - 65 Hence, 5 - 7 × 10 is greater.

Which is greater? - 3 - 4 × - 5 or - 3 - 4 × - 5

Given, - 3 - 4 × - 5 or - 3 - 4 × - 5 Simplify given two equations and check the greatest. - 3 - 4 × - 5 = - 3 - 4 × - 5 = - 7 × - 5 = 35 - 3 - 4 × - 5 = - 3 - - 20 = - 3 + 20 = 17 We see, 35 > 17 Hence, - 3 - 4 × - 5 is greater.
