๐ Understanding 4-0
The expression $4 - 0$ represents subtracting zero from four. Zero represents nothing, so you're essentially taking away nothing from four. Therefore, you are left with the same amount you started with.
- ๐ Imagine you have 4 apples.
- ๐๏ธ You don't give any away (subtracting 0).
- ๐ You still have 4 apples! $4 - 0 = 4$
๐ง Understanding 4-1
The expression $4 - 1$ represents subtracting one from four. You start with four, and then you take away one. This is a basic subtraction operation.
- โฝ Imagine you have 4 soccer balls.
- ๐ You give one away (subtracting 1).
- ๐ You now have 3 soccer balls! $4 - 1 = 3$
