Subtraction

What is Subtracting?


Have you ever given away some of your toys or candies to a friend? When you do that, you're subtracting! Let’s see: if you have 4 cubes, and you give 3 cubes to your friend, how many cubes do you have left?
\(\quad\)

Now you have 1 cube left! In math, we write it like this:$$4-3=1$$
\(-\) \(=\)


Definition Subtraction
Subtraction means taking something away. When we subtract, we find out how many are left.
  • The \(-\) symbol means "subtract."
  • The \(=\) symbol shows that the two sides are the same.
We can represent subtraction as:
  • Numbers: \(4 - 3 = 1\)
  • Cubes: \(-\) \(=\)
  • Fingers: \(-\) \(=\)
  • Words: four minus three equals one

How to Subtract?

Method Using the fingers
We want to find out what \(5-2\) is. Let’s use our fingers!
  • Hold up 5 fingers:
  • Put down 2 fingers:
  • Count how many fingers are still up: \(3\)
So, \(5-2=3\).
