On a number line, numbers always increase (become "more positive") to the right and decrease (become "more negative") to the left. Numbers to the right are greater than numbers to the left and numbers to the left are less than numbers to the right. To describe one number as less than another, we use the symbol "<".

Comparing Positive and Negative Numbers

We can compare two different numbers by looking at their positions on the number line. For any two different places on the number line, the number on the right is greater than the number on the left. Note that every positive number is greater than any negative number.

What happens when you add a positive number to a negative number?

Subtracting a number is the same as adding its opposite. So, subtracting a positive number is like adding a negative; you move to the left on the number line. Subtracting a negative number is like adding a positive; you move to the right on the number line.

Do 2 positives make a negative?

When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.

What is the rule for subtracting negative numbers?

Rule 3: Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.
