You can visualize positive & negative integers using the number line.

Do you know what is a integer

The temperature can rise or fall. Locations in the earth can be above sea level, or below sea level.

An integer is a whole number that can be either greater than 0, called positive, or less than 0, called negative. Zero is neither positive nor negative. Two integers that are same distance from the origin in opposite directions are called opposites.

The arrows on each end of the number line show us that the line stretches to infinity in both the negative and positive direction. We don't have to include a positive sign (+) when we write positive numbers. However, we do have to include negative sign (-) when we write negative numbers. Zero is called origin, and it's neither negative nor positive.

For every positive integer there is a negative integer an equal distance from the origin. Two integers lie the same distance from the origin in opposite directions are called opposites. For example, "negative 5" is the opposite of "positive 5."

Every number in the number line also has an absolute value, which simply means how far that number is from zero. The symbol for absolute value is two vertical lines. Since opposites are same distance from the origin, they have the same absolute value.Amazing Math

For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10. The absolute value of zero is zero.
