To add \(54 + (-24)\) using a number line, you can follow these steps:
-
Start at 54: Locate the number 54 on the number line.
-
Move Left: Since you're adding a negative number (-24), you will move to the left on the number line. Moving left corresponds to subtracting.
-
Count 24 Units: From 54, move left 24 units.
- Start at 54:
- 54 to 53 (1 unit)
- 53 to 52 (2 units)
- 52 to 51 (3 units)
- 51 to 50 (4 units)
- 50 to 49 (5 units)
- 49 to 48 (6 units)
- 48 to 47 (7 units)
- 47 to 46 (8 units)
- 46 to 45 (9 units)
- 45 to 44 (10 units)
- 44 to 43 (11 units)
- 43 to 42 (12 units)
- 42 to 41 (13 units)
- 41 to 40 (14 units)
- 40 to 39 (15 units)
- 39 to 38 (16 units)
- 38 to 37 (17 units)
- 37 to 36 (18 units)
- 36 to 35 (19 units)
- 35 to 34 (20 units)
- 34 to 33 (21 units)
- 33 to 32 (22 units)
- 32 to 31 (23 units)
- 31 to 30 (24 units)
- Start at 54:
-
Result: After moving 24 units to the left from 54, you arrive at \(30\).
Thus, \(54 + (-24) = 30\).
