Question

Theories on dividing by "0". I think its infinity what about you?

Answer 1

Hello from MrBillDoesMath!

Answer:  The quotient is not a number at all. It's simply undefined.

Discussion:

Consider the numbers "a" and "b" and further suppose that

a/0 = b

Multiplying both sides by 0 gives

(a/0) * 0 = b * 0

Cancelling the highlighted 0s gives a = 0!. Something is wrong here as  "a" is not equal to zero!  The error was produced by assuming the divison by 0 yield a number.

You will encounter this "divide by zero" matter several times in a Calculus courses.
