Question

Using the number line, what is the result of −13−(−12)?
a) −25
b) −1
c) 1
d) 25

Answer 1

The result of −13−(−12) is −1, which is option b). This is calculated by moving 13 units left for −13 and then 12 units right for subtracting a negative twelve.

Step-by-step explanation:

The question asks for the result of the expression −13−(−12) using a number line. To solve this, you would move 13 units to the left of zero for the −13. Then, because subtracting a negative is the same as adding its positive, you would move 12 units to the right (since −(−12) equals +12). This will bring you to one unit to the left of zero, which is −1. So, the answer is b) −1.
