Let's solve the expression step by step:

$-3 - 2 \times (4 - 6)$

1. Evaluate inside the parentheses first:

$4 - 6 = -2$

2. Substitute this result back into the expression:

$-3 - 2 \times (-2)$

3. Multiply $-2$ by $-2$:

$-2 \times (-2) = 4$

4. Finally, subtract 3 from 4:

$-3 + 4 = 1$

So, the result of the expression is $\boxed{1}$.

2. Can you simplify $3 \times (4 - 7) + 2$ and explain each step?
3. What happens if you change the numbers in the parentheses to $6 - 4$ instead of $4 - 6$?
4. How would you solve $-3 - 2(6 - 4)$?
