Imagine you have 6 delicious strawberries on your plate, and you eat 2 of them for a snack.
When we subtract, we start with a whole group and take some away to see how many are left.
Subtracting from Six
Let's find out how many strawberries are left by solving 6β2.

You had 6, crossed out 2, and 4 are left, so 6β2=4.
Did you know that addition can secretly help you solve subtraction in a flash?
Think Addition to Subtract
When you see a mystery like 6β4=?, flip it around and ask: "What number plus 4 makes 6?"

Since you already know that 4+2=6, you instantly know that 6β4=2!
What happens if we add one more to start with, giving us a whole group of 7?
