Use a number line to add 54+(−24) (1 point)
To add 54 + (-24) on a number line, start at the number 54 and move 24 units to the left since -24 means moving to the left on the number line.
Starting at 54, count backwards 24 units: 53, 52, 51, ..., 30, 29, 28.
The final result is 28.
To use a number line to add 54 and -24, follow these steps:
1. Start by drawing a number line with positive numbers to the right and negative numbers to the left.
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
2. Locate the number 54 on the number line by either counting from zero or using the labeled positive numbers.
3. Since we have to add -24 to 54, move 24 units to the left (since it's a negative number).
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
↑
-24
4. Starting from the point where you landed after moving 24 units to the left, move 24 units to the right (since it's a positive number).
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
↑
-24 ↑
+ 24
5. The point you land on after moving 24 units to the right is the answer. In this case, it is 30.
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
↑
+ 30
Therefore, 54 + (-24) equals 30.
