Question

there is a number line with a mark at 12, an arrow pointing left labeled -19.

Explanation:

Step1: Identify the operation

We need to find the result of moving from 12 by -19 (which means moving 19 units to the left on the number line). The operation is \( 12 + (-19) \) or \( 12 - 19 \).

Step2: Perform the subtraction

Calculate \( 12 - 19 \). Since 19 > 12, the result will be negative. \( 19 - 12 = 7 \), so \( 12 - 19 = -7 \).

Answer:

\( -7 \)
