Solve 8 + 8 ÷ 4 + 8 × 2 - 4 =?

Concept: BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction) fixes the order in which the operations in an arithmetic expression must be carried out: resolve any brackets first, then powers or roots, then all division and multiplication reading left to right, and only after that all addition and subtraction reading left to right.

Application — apply the rule to this expression:

1. Write down the expression: 8 + 8 ÷ 4 + 8 × 2 − 4.

2. There are no brackets or powers, so scan left to right for division and multiplication first: 8 ÷ 4 = 2.

3. Continue the division/multiplication pass: 8 × 2 = 16.

4. Substitute both results back into the expression: 8 + 2 + 16 − 4.

5. Now perform the addition and subtraction left to right: 8 + 2 = 10.

6. 10 + 16 = 26.

7. 26 − 4 = 22.

Cross-check by grouping the same four terms differently: (8 + 16) + (2 − 4) = 24 + (−2) = 22 — the same result, confirming the value.
