You Can't Divide by Zero

(inspired by Peter Gzowski interview with a singing math teacher from Ontario, second verse by Peter Robbins, Kwantlen University College, modified by me.)

(Tune : Rudolf the Red Nosed Reindeer)

Zero's a lovely number.
It will multiply and add just fine,
But you can't divide by zero
'Cause the answer's undefined.
All of the other numbers
Multiply and divide with ease
but if you divide by zero
all your calculator says is E

Perimeter Song

(Tune: O Christmas Tree)

The perimeter of a rectangle
is two lengths plus two widths.
The perimeter of a triangle
is the sum of all the sides.
The perimeter of a circle
is also called the circumference.

I is P R T (I is Pretty)

(Tune: I feel pretty-from Westside Story)

I is P R T (I is pretty)
Interest equals
Principa-al times ra-ate times time
I is P R T (I is pretty)
Calculates simple inter-est just fine.
