Let’s solve each expression step by step using the
order of operations (PEMDAS: Parentheses, Exponents, Multiplication/Division from left to right, Addition/Subtraction from left to right).
---
We’ll go one by one:
1) `2 + 7`
Just addition →
2 + 7 = 9
✔ Final answer for #1:
9
---
2) `14 - 8 + 2 - 6 + 7`
Only addition and subtraction — do them left to right:
- 14 - 8 = 6
- 6 + 2 = 8
- 8 - 6 = 2
- 2 + 7 = 9
✔ Final answer for #2:
9
---
3) `(7 + 3) ÷ 2`
Parentheses first:
7 + 3 = 10
Then divide:
10 ÷ 2 = 5
✔ Final answer for #3:
5
---
4) `6 + 2 - 6 + 9`
Left to right:
- 6 + 2 = 8
- 8 - 6 = 2
- 2 + 9 = 11
✔ Final answer for #4:
11
---
5) `8 - 6 + 7`
Left to right:
- 8 - 6 = 2
- 2 + 7 = 9
✔ Final answer for #5:
9
---
6) `10 ÷ 2 × 9`
Division and multiplication — left to right:
- 10 ÷ 2 = 5
- 5 × 9 = 45
✔ Final answer for #6:
45
---
7) `(10) ÷ 2 × 3²`
First, parentheses: (10) is just 10.
Exponent next: 3² = 9
Now: 10 ÷ 2 × 9
Left to right:
- 10 ÷ 2 = 5
- 5 × 9 = 45
✔ Final answer for #7:
45
---
Wait — let me double-check problem #7 because it says “(10) ÷ 2 × 3²” — yes, exponent comes before division/multiplication? Actually no — in PEMDAS, exponents come after parentheses but before multiplication/division. So we did it right:
Step 1: Evaluate exponent → 3² = 9
Step 2: Now expression is 10 ÷ 2 × 9
Step 3: Left to right → 10 ÷ 2 = 5; 5 × 9 = 45 ✔️

Also note: There’s a strip that just says “45” — that’s likely the answer to #6 or #7.
And there’s a strip with “×9” — probably part of #6.
Another strip says “9” — matches several answers.
---
Let’s list all final answers clearly:
1) 2 + 7 =
9
2) 14 - 8 + 2 - 6 + 7 =
9
3) (7 + 3) ÷ 2 =
5
4) 6 + 2 - 6 + 9 =
11
5) 8 - 6 + 7 =
9
6) 10 ÷ 2 × 9 =
45
7) (10) ÷ 2 × 3² =
45
---
Final Answer:
1) 9
2) 9
3) 5
4) 11
5) 9
6) 45
7) 45
