Use a number line to add 54+(−24).(1 point
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.
To add 54 and -24 using a number line, start by drawing a horizontal line labeled with numbers. Label the line from left to right, starting with the negative numbers and ending with the positive numbers. Make sure to label the numbers at equal intervals.
On the number line, locate the number 54. Mark it with a dot or a small tick. Since it's a positive number, it will be to the right of zero.
Next, locate -24 on the number line. Since it's a negative number, it will be to the left of zero. Mark it with a dot or a small tick.
Now, count forward from 54 to -24 by moving to the left. Since we are subtracting a negative number (-24), moving to the left actually means moving to the right on the number line.
Start at 54 and count 1 unit to the right. This brings you to 53. Continue moving to the right and count 20 units. This brings you to 33. Keep moving to the right and count 4 more units. This brings you to 29. Lastly, move to the right and count 20 more units. This brings you to 9.
So, the sum of 54 and -24 is equal to 9.
