# Change

2 quarters and 3 pennies is how much?
That is, let me think, 53.

1 dime, 3 nickels, and a 1 penny, how much is that?
10 plus 15 - 20 - 25 and one more 26!

Now let's make change
Uh, aren't we done yet.

If I give you \$1.00 and the candy costs 87 cents what is the change?
What do you mean?

What coins do I get back?
Oh. How do I do that again?

Count up 1-2-3 to 90 and then 10 more to 100.
That's backwards.

No that's change.

Background: Eddy is one of the magical hands that is tasked with transcribing class notes so students can focus on the information they are learning. The notes are then available after the class for study. That can lead to some comical documents as the young students try to build their craft. This student, Supheli Rend, was not particularly interested in the lesson that day. The sage was trying to teach the counting of money using an archaic coin system. The emphasis in lessons is that the mathematics is universal so whatever counting system is used, students can navigate standard mathematical methods.
