1. 20 + 8 × 4 = ___
First, do multiplication:
8 × 4 = 32
Then add:
20 + 32 =
52
✔ Final Answer for #1:
52

2. 7 × 6 + 4 × 4 = ___
Do both multiplications first (left to right):
7 × 6 = 42
4 × 4 = 16
Now add:
42 + 16 =
58
✔ Final Answer for #2:
58
---
3. 42 ÷ 7 + 8 × 8 = ___
Do division and multiplication first (left to right):
42 ÷ 7 = 6
8 × 8 = 64
Now add:
6 + 64 =
70
✔ Final Answer for #3:
70

4. 15 + 9 × 5 + 15 = ___
Multiplication first:
9 × 5 = 45
Now add left to right:
15 + 45 = 60
60 + 15 =
75
✔ Final Answer for #4:
75
---
5. 7 × 7 + 4 × 3 = ___
Multiplications first:
7 × 7 = 49
4 × 3 = 12
Add:
49 + 12 =
61
✔ Final Answer for #5:
61
---
6. 36 ÷ 6 × 5 = ___
Division and multiplication are done left to right:
36 6 = 6
6 × 5 =
30
✔ Final Answer for #6:
30
---
7. 82 - 9 × 9 + 20 = ___
Multiplication first:
9 × 9 = 81
Now go left to right with subtraction and addition:
82 - 81 = 1
1 + 20 =
21
✔ Final Answer for #7:
21
---
8. 4 × 12 + 3 × 4 = ___
Multiplications first:
4 × 12 = 48
3 × 4 = 12
Add:
48 + 12 =
60
✔ Final Answer for #8:
60
---
9. 6 × 12 + 3 × 3 = ___
Multiplications first:
6 × 12 = 72
3 × 3 = 9
Add:
72 + 9 =
81
✔ Final Answer for #9:
81
---
10. 12 + 12 × 12 = ___
Multiplication first:
12 × 12 = 144
Then add:
12 + 144 =
156
✔ Final Answer for #10:
156
---
Final Answer:
1. 52
