Order of operations
BIDMAS tells you the order to do a calculation: Brackets, Indices, Divide and Multiply (left to right), then Add and Subtract (left to right).
Brackets
2 × (3 + 4) = 2 × 7 = 14
Indices
5 + 2² = 5 + 4 = 9
Divide and Multiply (equal priority, left to right)
20 ÷ 4 × 3 = 5 × 3 = 15
Add and Subtract (equal priority, left to right)
10 − 4 + 6 = 6 + 6 = 12
