Representing
First, let's represent 23 with our base-10 notation
That's two tens and 3 ones
Or 2 fries and 3 tots

French Fries
There are 2, 4, 6 fries
That's 6 tens or ...
60

Tater Tots
There are 3, 6, 9 tater tots
That's 9 ones or...
9

Add it up
So we have 6 tens and 9 ones
AKA
60 + 9
AKA 69
So 23 x 3 = 69
