Answer to Q115:
10 - 2 x 4 ÷ 2 + 1
According to BODMAS (Bracket Order Division Multiplication Addition Subtraction), we have to attend to the Division first.
4 ÷ 2 = 2
So, it becomes
10 - 2 x 2 + 1
So we do the multiplication
- 2 x 2 = -4
So we have
10 - 4 + 1
So we do the addition
-4 + 1 = -3
So, we have
10 - 3 = 7
