Let’s solve each problem one by one, step by step.
---
1. (11 - 4) - 3
First, do what’s inside the parentheses:
11 - 4 = 7
Then subtract 3:
7 - 3 =
4
---
2. 2 + (12 - 1)
Parentheses first:
12 - 1 = 11
Then add 2:
2 + 11 =
13
---
3. 6 - 3 + 7
No parentheses — go left to right:
6 - 3 = 3
3 + 7 =
10
---
4. 17 - (6 + 6)
Parentheses first:
6 + 6 = 12
Then subtract from 17:
17 - 12 =
5
---
5. 14 - (17 - 5)
Parentheses first:
17 - 5 = 12
Then subtract from 14:
14 - 12 =
2
---
6. 5 + (12 - 2)
Parentheses first:
12 - 2 = 10
Then add 5:
5 + 10 =
15
---
7. 15 - (7 + 2)
Parentheses first:
7 + 2 = 9
Then subtract from 15:
15 - 9 =
6
---
8. 5 + (4 - 1)
Parentheses first:
4 - 1 = 3
Then add 5:
5 + 3 =
8
---
9. 12 - 3 - 6
Left to right:
12 - 3 = 9
9 - 6 =
3
---
10. 16 - 4 + 8
Left to right:
16 - 4 = 12
12 + 8 =
20
---
11. 14 + (11 - 8)
Parentheses first:
11 - 8 = 3
Then add 14:
14 + 3 =
17
---
12. 1 - (11 - 10)
Parentheses first:
11 - 10 = 1
Then subtract from 1:
1 - 1 =
0
---
13. 16 - (9 + 3)
Parentheses first:
9 + 3 = 12
Then subtract from 16:
16 - 12 =
4
---
14. 18 - (2 + 4)
Parentheses first:
2 + 4 = 6
Then subtract from 18:
18 - 6 =
12
---
15. 17 - (11 + 5)
Parentheses first:
11 + 5 = 16
Then subtract from 17:
17 - 16 =
1
---
16. 5 + (11 - 6)
Parentheses first:
11 - 6 = 5
Then add 5:
5 + 5 =
10
---
Final Answer:
1. 4
2. 13
3. 10
4. 5
5. 2
6. 15
7. 6
8. 8
9. 3
10. 20
11. 17
12. 0
13. 4
