A

7*(1)(14) = 98 Not the right answer. I have done what is inside the brackets first. (5 - 4) = 1; (5 + 9)= 14; 7 * 1 * 14 = 98 which is not 6

B

7 * [1 * 5] + 9 = 44; 7 * 5 + 9 = 35 + 9 = 44 Also not 6

C

7*[5 - 20 + 9] = - 42; Not 6 as well 7*[14-20] = 7*-6 = - 42

D

7*5 - [20 + 9] = 35 - 29 = 6

Answer D


B - Bracket O - Order D - Division M - Multiplication A - Addition S - Subtraction

The last option (7 * 5) - [(4 * 5) + 9]

In Order so you do the first bracket

7 * 5 = 35

Then in the second bracket, you see (4 * 5) + 9

Bracket before addition so,

4 * 5 = 20 20 + 9 = 29

35 - 29 = 6
