➕ Topic Summary
Subtraction is taking away a number from another. When we use the standard algorithm for subtraction without regrouping, it means we are subtracting numbers where the digit on the top is always bigger than the digit on the bottom in each column (ones, tens, hundreds, etc.). This makes it easier because we don't have to 'borrow' from the next column!
Think of it like this: If you have 5 apples 🍎 and you eat 2, you're left with 3 apples. That's subtraction! We're just doing it with bigger numbers now, but one column at a time.
