Start with -5 and go 3 to the right.
-5 + 3 = -2
To use a number line to determine −5−(−3), we can visualize it step by step as follows:
1. Start by locating the point representing -5 on the number line. Assume this is represented by a dot.
2. Move 3 units to the left from the point representing -5 to reach -3. Mark this point as well.
3. Now, we want to find the difference between -5 and -3. Since the expression is -5 - (-3), we can interpret it as subtracting a negative number. Subtracting a negative is the same as adding a positive, so we can rephrase the expression as -5 + 3.
4. Starting from the point representing -5 on the number line, move 3 units to the right. This brings us to the point representing -2.
5. The difference between -5 - (-3) is simply -2. Therefore, -5 - (-3) = -2.
Using the number line, we can visually see the steps involved in subtracting a negative number, making it easier to understand the concept and arrive at the correct answer.
