To solve the equation 10 + (-7), we start at 10 on the number line and move 7 units to the left.
Since the arrow at the end of the number line indicates negative numbers, moving left represents subtracting.
Starting at 10, we subtract 1, 2, 3, 4, 5, 6, and 7 to the left.
The solution is 3.
Use the image to answer the question.
A number line with arrows at both ends ranges from negative 12 to 12. The numbers negative 12, 0, and 12 are labeled.
Solve the following equation: 10+−7
. Use the number line as a model to find the solution.
