- A. 6
- B. 8
- C. 10
- D. 12
Explanation: Replace the signs to get 20 × 3 ÷ 6 - 2. Working from left to right for multiplication and division gives 10 - 2 = 8.
Correct answer: 8- A. 14
- B. 16
- C. 18
- D. 20
Explanation: The expression becomes 48 ÷ 6 + 4 × 2. BODMAS gives 8 + 8, so the answer is 16.
Correct answer: 16- A. + and ×
- B. + and -
- C. × and -
- D. - and the number 6
Explanation: Interchanging × and - gives 15 + 4 - 2 × 6. This equals 15 + 4 - 12 = 7, while the other sign pairs do not give 7.
Correct answer: × and -- A. 32
- B. 35
- C. 38
- D. 40
Explanation: Inside the brackets, the expression becomes 30 - 8 ÷ 4 = 28. The remaining signs give 28 + 2 × 5 = 38.
Correct answer: 38- A. + and ÷
- B. + and -
- C. × and ÷
- D. - and ×
Explanation: Swap - and × to obtain (24 + 6) ÷ 3 × 2 - 4. BODMAS gives 30 ÷ 3 × 2 - 4 = 16.
Correct answer: - and ×- A. 13
- B. 15
- C. 17
- D. 19
Explanation: After substitution, it is (48 ÷ 8) × 3 - 4 + 2 ÷ 2. This becomes 6 × 3 - 4 + 1 = 15.
Correct answer: 15- A. + and ×
- B. + and -
- C. + and ÷
- D. - and ×
Explanation: Swap + and -. The equation becomes (24 - 8) × 3 + 6 ÷ 2 + 1, which equals 48 + 3 + 1 = 52. The other listed swaps give different results.
Correct answer: + and -- A. 24
- B. 27
- C. 30
- D. 33
Explanation: Replace the signs first: 18 × 3 ÷ 2. Multiplication and division are done from left to right, giving 27.
Correct answer: 27- A. 20
- B. 22
- C. 24
- D. 26
Explanation: The expression becomes 25 - 7 + 4. Working from left to right gives 18 + 4, which equals 22.
Correct answer: 22- A. 45
- B. 48
- C. 51
- D. 54
Explanation: After substitution, the expression is 24 × 8 ÷ 4 + 3. Applying BODMAS gives 48 + 3, so the answer is 51.
Correct answer: 51- A. 11
- B. 13
- C. 15
- D. 17
Explanation: Substitution gives (45 ÷ 5) - 3 + 7. The bracket is 9, so 9 - 3 + 7 equals 13.
Correct answer: 13- A. 15
- B. 17
- C. 19
- D. 21
Explanation: The substituted expression is 35 - 7 × 6 ÷ 2 + 3. BODMAS gives 35 - 21 + 3, which equals 17.
Correct answer: 17- A. + and ×
- B. + and ÷
- C. - and ×
- D. - and ÷
Explanation: Interchanging - and ÷ gives 12 + 6 × 4 ÷ 8 - 2. Applying BODMAS produces 12 + 3 - 2, which equals 13.
Correct answer: - and ÷- A. 13
- B. 15
- C. 17
- D. 19
Explanation: The expression changes to (56 ÷ 7 - 3) + 2 × 5. The bracket equals 5 and 2 × 5 equals 10, giving 15.
Correct answer: 15- A. + and -
- B. + and ×
- C. + and ÷
- D. - and ×
