Question

Determine the result of (-5) + 4 and explain the steps using a number line.

A. -1
B. 0
C. 1
D. 9

Answer 1

The result of (-5) + 4 is -1, which is obtained by starting at -5 on a number line and moving 4 units to the right, landing on -1.

Step-by-step explanation:

To determine the result of (-5) + 4, let's use a number line as a visual aid. You start at -5 on the number line since that is the first number in the expression. Then you will move 4 units to the right because you are adding 4. Moving to the right indicates increasing value or adding positive numbers. After moving 4 units to the right from -5, you land on -1. Therefore, the result of (-5) + 4 is -1.

Here is how you visualize it step by step:

1. Locate the point -5 on the number line.
2. Since you are adding a positive number, move 4 units to the right.
3. The point you reach after this movement is -1.

Thus, the given operation shows subtraction of a negative number which is similar to the addition of a positive number. The correct answer is A. -1.
