4 + 2 x 3 ÷ 6 = 3
or
4 + 2 x 3 ÷ 6 = 5

7. 7
In performing series of operations, we
follow the GEMDAS:
G – Grouping symbols such as
( ), [ ], { }.
E – Exponent
M – Multiplication
D g– Division
A – Addition
Perform whichever

4 + 2 x 3 ÷ 6 = n
4 + 6 ÷ 6 = n
4 + 1 = 5

9. 9
4 + 2 x 3 ÷ 6 = 3
or
4 + 2 x 3 ÷ 6 = 5

10. 10
Example:
32 – 16 x 3 ÷ 8 + 14 = n
32 – 48 ÷ 8 + 14 = n
32 – 6 + 14 = n
26 + 14 = n

11. 11
Example:
25 + 32 x (12 – 8) ÷ 6 = n
25 + 32 x 4 ÷ 6 = n
25 + 9 x 4 ÷ 6 = n
25 + 36 ÷ 6 = n
25 + 6 = n
