Let’s solve each problem step by step using the
order of operations:
> Remember:
>
Multiply and divide first (from left to right),
> then
add and subtract (also from left to right).

Problem 1:
2 - 7 × 8 + 10
Step 1: Multiply → 7 × 8 = 56
Now: 2 - 56 + 10
Step 2: Left to right → 2 - 56 = -54
Then: -54 + 10 =
-44
✔ Answer:
-44

Problem 2:
33 × 8 ÷ 3 - 1
Step 1: Multiply → 33 × 8 = 264
Then divide → 264 ÷ 3 = 88
Now: 88 - 1 =
87
✔ Answer:
87

Problem 3:
5 + 5 × 10 - 5
Step 1: Multiply → 5 × 10 = 50
Now: 5 + 50 - 5
Step 2: Left to right → 5 + 50 = 55
Then: 55 - 5 =
50
✔ Answer:
50

Problem 4:
8 + 20 × 5 ÷ 10
Step 1: Multiply → 20 × 5 = 100
Then divide → 100 ÷ 10 = 10
Now: 8 + 10 =
18
✔ Answer:
18
---
Problem 5:
3 + 11 + 11 × 2
Step 1: Multiply → 11 × 2 = 22
Now: 3 + 11 + 22
Step 2: Add left to right → 3 + 11 = 14; 14 + 22 =
36
✔ Answer:
36
---
Problem 6:
3 + 6 × 5 + 4
Step 1: Multiply → 6 × 5 = 30
Now: 3 + 30 + 4
Step 2: Add → 3 + 30 = 33; 33 + 4 =
37
✔ Answer:
37
---
Problem 7:
50 × 2 ÷ 10 + 7
Step 1: Multiply → 50 × 2 = 100
Then divide → 100 ÷ 10 = 10
Now: 10 + 7 =
17
✔ Answer:
17
---
Problem 8:
2 + 18 × 3 ÷ 2
Step 1: Multiply → 18 × 3 = 54
Then divide → 54 ÷ 2 = 27
Now: 2 + 27 =
29
✔ Answer:
29
---
Problem 9:
10 × 5 ÷ 1 + 2
Step 1: Multiply → 10 × 5 = 50
Then divide → 50 ÷ 1 = 50
Now: 50 + 2 =
52
✔ Answer:
52
---
Problem 10:
6 × 6 ÷ 6 + 2
Step 1: Multiply → 6 × 6 = 36
Then divide → 36 ÷ 6 = 6
Now: 6 + 2 =
8
✔ Answer:
8
