This is something we all need to work on. It can be a little tricky and it is another word for subtraction. We are working out the difference between two measurements. We are taking away one measurement from the other? Please practice this at home.
If the tallest person in the world was 272cm,
How tall are you? What is the difference in height?
For example 272cm - 120 cm = 152 cm
The difference is over double the size. Wow! Are you under or over half the size of the tallest man in the world??
