Let's solve each problem step by step and write the correct
numerical expressions as instructed. Remember:
- Use `/` for division.
- Do
not put spaces.
- Follow the order of operations (PEMDAS) when needed.

1. Add 6 and 4, then multiply 2
→ First add: 6 + 4 = 10
Then multiply by 2: 10 × 2 = 20
But we need to write the
expression, not just the answer.
To ensure addition happens first, use parentheses:
(6+4)*2
✔ Answer:
(6+4)*2
---
2. Add 5 and 10, then divide by 2
→ (5 + 10) / 2
= 15 / 2
✔ Answer:
(5+10)/2
---
3. Subtract 8 from 19, then divide by 2
→ (19 - 8) / 2
= 11 / 2
✔ Answer:
(19-8)/2
---
4. Divide 16 by 2, then add 3
→ 16 / 2 + 3
= 8 + 3 = 11
But since division comes before addition in order of operations, no parentheses needed.
✔ Answer:
16/2+3
---
5. 3 more than 18 multiplied by 4
This means: (18 × 4) + 3
"18 multiplied by 4" → 18×4
"3 more than" → add 3
So:
(18*4)+3
✔ Answer:
(18*4)+3
---
6. Subtract 6 from 12, then multiply by 3
→ (12 - 6) × 3 = 6 × 3 = 18
Expression:
(12-6)*3
✔ Answer:
(12-6)*3
---
7. Add 9 and 14, then multiply 4
→ (9 + 14) × 4 = 23 × 4 = 92
Expression:
(9+14)*4
✔ Answer:
(9+14)*4
---
8. Divide 90 by 2, then add 27
→ 90 / 2 + 27 = 45 + 27 = 72
No parentheses needed because division comes first.
✔ Answer:
90/2+27
---
9. The sum of 12 and 4 multiply by 2
→ "Sum of 12 and 4" = 12 + 4
Then multiply by 2 → (12 + 4) × 2
= 16 × 2 = 32
✔ Answer:
(12+4)*2
---
10. The quotient of 16 and 4 plus 2
→ Quotient of 16 and 4 = 16 / 4 = 4
Then plus 2 → 4 + 2 = 6
But expression is:
16/4+2
✔ Answer:
16/4+2
---
✔ Final Answers:
1.
(6+4)*2
2.
(5+10)/2
3.
(19-8)/2
4.
16/2+3
5.
(18*4)+3
6.
(12-6)*3
7.
(9+14)*4
8.
90/2+27
9.
(12+4)*2
10.
16/4+2
> 💡 Note: Although some expressions can be evaluated, the task asks for
numerical expressions, not simplified answers. So we write the expression using symbols as described.
