Calculate: (18 - 6) / 4 + 7.
Answer:
10
Solve bracket: 18 - 6 = 12. Then division: 12 / 4 = 3. Finally addition: 3 + 7 = 10.
192
Simplify: 50 * 2 / 10 + 5.
Answer:
15
Division first: 2 / 10 = 0.2 (or do 50/10*2). Let's process left to right for mult/div: (50 * 2) / 10 = 100 / 10 = 10. Then 10 + 5 = 15.
193
Evaluate: 8 + 4 * 3 - 6 / 2.
Answer:
17
Division: 6 / 2 = 3. Multiplication: 4 * 3 = 12. Equation becomes 8 + 12 - 3 = 20 - 3 = 17.
194
Simplify: 60 / (12 - 2) * 3.
Answer:
18
Bracket first: 12 - 2 = 10. Then division: 60 / 10 = 6. Finally multiplication: 6 * 3 = 18.
195
Find the value of: 24 / 8 + 3 * 4.
Answer:
15
Perform division and multiplication: 24 / 8 = 3 and 3 * 4 = 12. Add the results: 3 + 12 = 15.
196
Calculate: 100 - 50 / 5 * 2.
Answer:
80
Division first: 50 / 5 = 10. Multiplication next: 10 * 2 = 20. Subtraction last: 100 - 20 = 80.
197
Simplify: (14 + 6) / 4 * 2.
Answer:
10
Solve the bracket first: 14 + 6 = 20. Then division: 20 / 4 = 5. Finally multiplication: 5 * 2 = 10.
198
Evaluate: 36 / 6 * 2 + 8.
Answer:
20
Follow BODMAS: Division first (36 / 6 = 6). Then multiplication (6 * 2 = 12). Then addition (12 + 8 = 20).
199
Find the value of 12 * 5 - 20 / 4.
Answer:
55
By BODMAS rule, first do division: 20 / 4 = 5. Then multiplication: 12 * 5 = 60. Finally, subtraction: 60 - 5 = 55.
200
Simplify the expression: 45 + 15 / 3.
Answer:
50
According to BODMAS, division is performed first. So, 15 / 3 = 5. Then, add 45 + 5 = 50.
