order is do the division first:
12/8=1.5
1.5*6=9
9+3=12

goldenstar - I will suggest that you understand the BIDMAS rule which will help you to solve any of such questions. The order of calculation is Bracket, Indices, Division, Multiply, Add and Subtract
Your question: If A = 3, B = 6, C = 8, D = 9, E = 12,
what is the answer to this sum written as a letter?
E/CxB + A
Step 1. Calculate "E/C" = 12/8 i.e. 3/2
Step 2. Calculate "X B" = 3/2 X 6 = 9
Step 3. Calculate "+A" = 9 + 3 = 12
Answer is 12
You can also try
4 X (3 square) + (12/2 - 3) - 5
4 X 9 + (6 - 3) -5
4 X 9 + (6 - 3) -5
36+3-5
39-5
Answer 34
