All about Subtracting Across Zero
When you subtract a larger number from a smaller one, the answer is negative. A number line helps show this, because you count down past zero into the negative numbers. Negative numbers are shown with a minus sign in front of them.
Temperatures are a common real example. If the temperature falls from 2 degrees to minus 3 degrees, the change is 5 degrees. Understanding negative numbers helps with money, sea levels and many science experiments.
