3. Let’s do the same problem the other way.
Line up the 70 on the outer ring with the 10
on the middle ring. Find the 50 on the middle
ring and look! It again reads 35! Remember,
it doesn’t matter which number you line up
with the 10 on the middle ring.
Practice these multiplication problems:
9 x 3 = 27 14 x 7 = 98
23 x 5 = 115 90 x 3 = 270
11 x 13 = 143 4 x 29 = 117
Division
For division problems, you will not be setting any
numbers under the 10 on the middle ring, because
that is where your answer is going to be! The
example below explains what I’m trying to say:
Example: 15/5
1. Whatever number is being divided will go on
the outer ring. Therefore in this example, find
15 on the outer ring.
