You’ve uploaded a worksheet titled
“Order of Operations”. This is a standard math exercise designed to practice the
PEMDAS/BODMAS rule:
>
Parentheses /
Brackets
>
Exponents /
Orders (powers, roots)
>
Multiplication and
Division (left to right)
>
Addition and
Subtraction (left to right)
We’ll solve each problem step by step using this rule.

Problem 1:
8 × (3 × 2 − 8) + 10
1. Inside parentheses:
→ 3 × 2 = 6
→ 6 − 8 =
−2
2. Multiply:
→ 8 × (−2) =
−16
3. Add:
→ −16 + 10 =
−6
✔ Answer: −6

Problem 6:
(10 + 20 − 2) − (11 + 3)
1. First parentheses:
→ 10 + 20 = 30 → 30 − 2 =
28
2. Second parentheses:
→ 11 + 3 =
14
3. Subtract:
→ 28 − 14 =
14
✔ Answer: 14

(9 − 5) × (15 + 15 − 3)
1. First parentheses:
→ 9 − 5 =
4
2. Second parentheses:
→ 15 + 15 = 30 → 30 − 3 =
27
3. Multiply:
→ 4 × 27 =
108
✔ Answer: 108
