Use a number line to add 54+(−24)

.(1 point

1 answer

To add \( 54 + (-24) \) using a number line, follow these steps:

  1. Start at 54: Begin at the point marked 54 on the number line.

  2. Move Left: Since you are adding a negative number (-24), you will move to the left on the number line. The distance you will move is 24 units.

  3. Calculate the New Position:

    • Starting from 54, moving left 24 units: \[ 54 - 24 = 30 \]

  4. Conclusion: The result of \( 54 + (-24) \) is \( 30 \).

So, on a number line, you would start at 54, move 24 units left, and end up at 30. Thus, the answer is \( 30 \).
