To add 54 and -24 using a number line, we can start by plotting 54 as a dot on the positive side of the number line and -24 as a dot on the negative side.
On the positive side, place 54 as a dot.

-24 | |
| |
-24 54
Then, we can take 24 steps to the left (or to the negative side) from the dot representing 54.

-24 |-----|---------|
| |
-24 54
This brings us to the dot representing -24.
Finally, we can count the total distance or steps between the two dots, which would be 54 steps to the right (positive side) and 24 steps to the left (negative side), resulting in a total of 30 steps to the right.
Therefore, 54 + (-24) = 30.
Use a number line to add 54+(−24).(1 point
