Absolutely! Let’s solve each of these integer expressions using
PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).
---
🔹 Left Column
---
1. `3 × 4 - 4 × (-7)`
→ Multiply first:
`3 × 4 = 12`
`4 × (-7) = -28`
→ Now subtract:
`12 - (-28) = 12 + 28 = 40`
✔ Answer: 40
---
2. `12 × (-2) - 11 + 2`
→ Multiply: `12 × (-2) = -24`
→ Now left to right: `-24 - 11 = -35`, then `-35 + 2 = -33`
✔ Answer: -33
---
3. `(-96) ÷ (-4) + (-9) - (-11)`
→ Divide: `(-96) ÷ (-4) = 24`
→ Now: `24 + (-9) = 15`, then `15 - (-11) = 15 + 11 = 26`
✔ Answer: 26
---
4. `(-3) + (-12) - (-3) - (-7)`
→ Simplify signs:
= `-3 -12 +3 +7`
→ Left to right: `-3 -12 = -15`, then `-15 +3 = -12`, then `-12 +7 = -5`
✔ Answer: -5
---
5. `2 + 11 + 66 ÷ 11`
→ Divide first: `66 ÷ 11 = 6`
→ Now add: `2 + 11 + 6 = 19`
✔ Answer: 19
---
🔹 Right Column
---
6. `(-3) × (-6) - (-12) + (-6)`
→ Multiply: `(-3) × (-6) = 18`
→ Now: `18 - (-12) = 18 + 12 = 30`, then `30 + (-6) = 24`
✔ Answer: 24
---
7. `(-8) - (-66) ÷ 11 + (-3)`
→ Divide first: `(-66) ÷ 11 = -6`
→ Now: `(-8) - (-6) = -8 + 6 = -2`, then `-2 + (-3) = -5`
✔ Answer: -5
---
8. `5 - 6 × 3 + 7`
→ Multiply: `6 × 3 = 18`
→ Now: `5 - 18 = -13`, then `-13 + 7 = -6`
✔ Answer: -6
---
9. `(-10) × (-9) + (-12) + (-3)`
→ Multiply: `(-10) × (-9) = 90`
→ Now: `90 + (-12) = 78`, then `78 + (-3) = 75`
✔ Answer: 75
---
10. `4 × 66 ÷ 11 + 12`
→ Left to right for multiplication/division:
`4 × 66 = 264`, then `264 ÷ 11 = 24`
→ Then `24 + 12 = 36`
✔ Answer: 36
