Expression Simplification 28Eb15
1. **State the problem:** Simplify the expression $4 \times 3 \times \frac{2}{-3} - (-1) \times 3 \times (-3) \times 2$.
2. **Recall the rules:**
- Multiplication and division are performed from left to right.
- Subtracting a negative number is equivalent to adding the positive.
- Pay attention to signs when multiplying or dividing.
3. **Calculate each part:**
- First part: $4 \times 3 = 12$
- Then multiply by $\frac{2}{-3}$: $12 \times \frac{2}{-3} = \frac{24}{-3} = -8$
4. **Calculate the second part:**
- $-(-1) = +1$
- Multiply $1 \times 3 = 3$
- Multiply $3 \times (-3) = -9$
- Multiply $-9 \times 2 = -18$
5. **Combine both parts:**
- $-8 - (-18) = -8 + 18 = 10$
**Final answer:** $10$
