Drag and drop each choice into the correct boxes to complete the description of how to find the sums -2 + 1 and -2 + (-1) on a number line

a. -1

b. -3

Explanation:

To solve negative and positive numbers on the number line, we make a simple analogy. If we wanted to -3+2 for instance:

Imagine a customer placed an order for 3 bags of apples from your store but you are out of stock and only have 2 bags left. You then come to an agreement with the customer to send 2 bags now and send the remaining one later in the week when your stock arrives from your supplier. In this way, you are only able to send two bags which you have,+2, and then be owing the customer one bag left(-1) to deliver out of the three, -3.

To solve -2+1 on the number line, with -2 on the left side of 0(negative) on the number line and +1 on the right side of 0(positive), we use same analogy above.

-2+1= -1

Also using same analogy, -2+(-1)= -3

Note: +1×-1=-1
