How to add 66 tens +120 ones+5 hundreds

Hello,

This was pretty tricky. :D

So, The first thing you want to do is to multiply 66 by 10. Were doing this because you have 66,10 times. So as we do that,your answer would be 
660

120 ones is automatically 120.

5 Hundreds will be 500.

So to sum it all up.

We have 660+120+500

And your answer would sum up to be . . .

1280.

Glad to help

66 tens converts into 660
120 ones converts into 120 
5 hundreds converts into 500.

660 + 120 = 780 + 500 = 1280. 

Hope this helps!
