Determine the answer to (−5) + 4 and explain the steps using a number line (5 points)

Answer 1

To determine the answer to (-5) + 4, we can use a number line to visualize the process.

1. Draw a horizontal line and mark a point labeled 0 in the center.
2. To the left of 0 on the number line, mark a point labeled -1, then another -2, -3, -4, and -5 in sequence.
3. To the right of 0, mark a point labeled 1, then another 2, 3, and 4 in sequence.

Now, let's start at -5 on the number line:

-5 -4 -3 -2 -1 0 1 2 3 4

4

Starting from -5, we want to move 4 units to the right. Each unit represents adding 1, so we need to add 4 units or 4 positive numbers.

-5 -4 -3 -2 -1 0 1 2 3 4
↑ ↑ ↑ ↑

After moving 4 units to the right, we land on the point labeled 4. Therefore, (-5) + 4 equals 4.

Thus, the answer is 4, as we started at -5 on the number line and moved 4 units to the right to reach 4.
