In our place value system, every digit represents a different value based on its position. The ones, tens, hundreds, and so on, all increase in value by factors of 10. When you have 10 tens, you actually have 10 × 10, which equals 100. Instead of carrying around 10 tens, it’s more efficient to regroup them into 1 hundred.

Here's what happens step by step:
1. You start with 10 tens.
2. Since 10 tens make 100, you take those 10 tens and convert them into 1 hundred.
3. The tens position then loses 10 tens (leaving 0 tens in that particular grouping), while the hundreds position increases by 1.

In summary, regrouping 10 tens into 1 hundred means that the number of tens decreases by 10, and the number of hundreds increases by 1.
When you have 10 tens, you can regroup them into 1 hundred. This means the number of tens decreases by 10, and the number of hundreds increases by 1.
