You’ve uploaded an image of a math worksheet titled
“DMAS”, which stands for
Division, Multiplication, Addition, Subtraction — the order of operations for simplifying arithmetic expressions (a simplified version of PEMDAS/BODMAS, without parentheses or exponents).
The worksheet asks to
evaluate each expression using DMAS rules.
---
Let’s solve each problem step by step, applying
DMAS: left to right, but with division and multiplication done before addition and subtraction.
---
1. 15 ÷ 3 + 4
- First, do division:
15 ÷ 3 = 5
- Then, add:
5 + 4 = 9
✔ Answer: 9
---
2. 35 ÷ 5 × 4 – 1
- Left to right for same precedence (÷ and × have same priority):
35 ÷ 5 = 7
7 × 4 = 28
- Then subtract:
28 – 1 = 27
✔ Answer: 27
---
3. 10 – 4 × 2
- Multiplication first:
4 × 2 = 8
- Then subtract:
10 – 8 = 2
✔ Answer: 2
---
4. 8 × 12 – 10
- Multiplication first:
8 × 12 = 96
- Then subtract:
96 – 10 = 86
✔ Answer: 86
---
5. 25 + 4 × 5
- Multiplication first:
4 × 5 = 20
- Then add:
25 + 20 = 45
✔ Answer: 45
---
6. 6 – 40 ÷ 4
- Division first:
40 ÷ 4 = 10
- Then subtract:
6 – 10 = -4
✔ Answer: -4
---
7. 51 + 60 ÷ 3
- Division first:
60 ÷ 3 = 20
- Then add:
51 + 20 = 71
✔ Answer: 71
---
8. 60 ÷ 5 – 10
- Division first:
60 ÷ 5 = 12
- Then subtract:
12 – 10 = 2
✔ Answer: 2
---
9. 40 ÷ 4 + 10
- Division first:
40 ÷ 4 = 10
- Then add:
10 + 10 = 20
✔ Answer: 20
---
10. 20 – 12 × 3
- Multiplication first:
12 × 3 = 36
- Then subtract:
20 – 36 = -16
✔ Answer: -16

## 📌 Key Concept Reminder:
In
DMAS, you follow this order:
-
Division
-
Multiplication
-
Addition
-
Subtraction
But note:
Division and Multiplication are equal in priority — perform them
left to right. Same for
Addition and Subtraction.
This is why in problem #2: `35 ÷ 5 × 4 – 1` → we did `(35 ÷ 5) = 7`, then `7 × 4 = 28`, then `-1`.
Always remember:
Do higher-precedence operations first, then left to right for same level.
