Writing the expression and then evaluating it — that pairing locks the translation in. You will turn 'subtract 9 from 15, then multiply by 7' into (15 − 9) × 7 and compute 42, write (8 + 12) ÷ 10 and find 2, and handle 'multiply 7 by 6, then subtract 22' end to end.
You will also evaluate (16 − 4) × (18 ÷ 6) and match four word phrases — including 'subtract 3 from 11, then multiply by 5' and 'divide 30 by 5, then add 14' — to their parenthetical forms. Doing both halves cements that the parentheses control which operation runs first.

Numerical Expressions
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Write an expression: Subtract 9 from 15, then multiply by 7. Answer: (15 − 9) × 7
2. Evaluate: (15 − 9) × 7 = 42
3. Write an expression: Add 8 and 12, then divide by 10. Answer: (8 + 12) ÷ 10
4. Evaluate: (8 + 12) ÷ 10 = 2
5. Write an expression: Multiply 7 by 6, then subtract 22. Answer: (7 × 6) − 22
6. Evaluate: (7 × 6) − 22 = 20
7. Write an expression: Divide 45 by 9, then add 15. Answer: (45 ÷ 9) + 15
8. Evaluate: (45 ÷ 9) + 15 = 20
9. Evaluate: (16 − 4) × (18 ÷ 6) = 36
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Subtract 3 from 11, then multiply by 5
→ (11 − 3) × 5
(4 × 8) − 12
Add 9 and 6, then divide by 3
→ (9 + 6) ÷ 3
(30 ÷ 5) + 14
Multiply 4 by 8, then subtract 12
→ (4 × 8) − 12
(11 − 3) × 5
Divide 30 by 5, then add 14
→ (30 ÷ 5) + 14
(9 + 6) ÷ 3
