Subtracting integers - Adding and Subtracting Integers

Subtracting integers

In previous sections, we use number lines with arrows to represent given statements. We also learned addition statements. In this section, we are looking at subtraction statements. A thermometer is just like a number line, except thermometers are vertical. As the line on a thermometer moves down, the temperature gets cooler and as the line moves up, the temperature gets warmer. In this section, the blue arrows on the number line will move to the left, or down the number line, and represent negative integers. The red arrows will move to the right, or up the number line, and represent positive integers.
