Using a number line, what is the sum of −13+10?
To find the sum of -13 + 10 using a number line, we start at -13 and move 10 units in the positive direction:
-13 + 10 = -3
So, the sum of -13 + 10 is -3.
To find the sum of −13+10 using a number line, follow these steps:
1. Start at 0 on the number line.
2. Move 13 units to the left to reach −13.
3. From −13, move 10 units to the right (since 10 is positive) to reach −3.
(Alternatively, you can also think of this as subtracting 10 from −13.)
Therefore, the sum of −13+10 is −3.
