To solve the problem $-10 - 2$, we can represent it on the number line.

1. Start at $-10$: Plot this point on the number line.
2. Subtract 2: Subtraction means moving two steps to the left on the number line. From $-10$, if you move two steps left, you land at $-12$.

Thus, the result is:

$-10 - 2 = -12$

Visualization on the number line:

1. Start at $-10$.
2. Move left by two units:
   • First step: $-11$
   • Second step: $-12$
