5 tens +5 tens=

Question

Needs to be answered in standard form.

Answer 1

Well, first ask yourself, what is 5 tens?

5 tens is equal to 50.

 

So, then what is 50 + 50?

Answer 2

This problem is intended to help you learn about units, tens, hundreds, thousands, and so on in a positional numbering system like decimal.

 

Just like 5 dollars + 5 dollars = 10 dollars (and you might want to trade it for a $10 bill now),  5 tens + 5 tens = 10 tens (and they have $100 bills, too).
