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
