Multiplication
Whenever you want to multiply something quickly
you can use your Abingdon watch. To do so, you
must set one of the numbers on the outer ring to the
10 on the middle ring. It doesn’t matter which one.
For example, 5 x 7 (we’re going to start off easy)
1.
Rotate the number 50 on the outer ring to the
number 10 on the middle ring. (notice that
there is not a “5” on the outer ring? We are
going to treat 50 like it is actually 5.0). Leave
it there.
