Problem 1: 14 + (87 × 10) + 30
Step 1: Do what’s in parentheses:
87 × 10 = 870
Step 2: Now add left to right:
14 + 870 = 884
884 + 30 =
914
✔ Final Answer for Problem 1:
914

Problem 2: 11 × 2 × 4 – 54
Step 1: Multiply left to right:
11 × 2 = 22
22 × 4 = 88
Step 2: Subtract:
88 – 54 =
34
✔ Final Answer for Problem 2:
34

Problem 3: 62 + 97 – (79 – 51)
Step 1: Parentheses first:
79 – 51 = 28
Step 2: Add and subtract left to right:
62 + 97 = 159
159 – 28 =
131
✔ Final Answer for Problem 3:
131

Problem 4: (1 × 3 + 51) – 3
Step 1: Inside parentheses — do multiplication first:
1 × 3 = 3
Then add: 3 + 51 = 54
Step 2: Subtract outside:
54 – 3 =
51
✔ Final Answer for Problem 4:
51
---
Problem 5: (12 × 12 ÷ 48) + 93
Step 1: Inside parentheses — multiply and divide left to right:
12 × 12 = 144
144 ÷ 48 = 3
Step 2: Add:
3 + 93 =
96
✔ Final Answer for Problem 5:
96
---
Problem 6: 78 + 90 – (36 + 41)
Step 1: Parentheses first:
36 + 41 = 77
Step 2: Add and subtract left to right:
78 + 90 = 168
168 – 77 =
91
✔ Final Answer for Problem 6:
91
---
Problem 7: (96 – 91 + 71) × 6
Step 1: Inside parentheses — go left to right:
96 – 91 = 5
5 + 71 = 76
Step 2: Multiply:
76 × 6 =
456
✔ Final Answer for Problem 7:
456
---
Problem 8: 112 ÷ 16 + (66 ÷ 33)
Step 1: Do divisions first (including inside parentheses):
112 ÷ 16 = 7
66 ÷ 33 = 2
Step 2: Add:
7 + 2 =
9
✔ Final Answer for Problem 8:
9
