Question

Regroup to express the number in a different way.

Answer 1

This is one of those problems where the way it is worded is more confusing than the actual problem. You’ve got this.

100 x 10 = 1,000

So when they took away one thousand, they added 10 hundreds. So now you have
8 thousands
11 hundreds
And 5 tens

Does that make sense? Happy to explain more if needed.
