I don't disagree with dividing by 0 or infinity, but you can't do it using our numbers. Doing so would be like trying to divide two imaginary numbers and trying to end up with a real number. What I would say is multiply both sides by 10 ^ ∞ and end up with 1 = 0... I don't think they are the same, but it's ok... :) I read what you said, and it makes sense too... Here is an extra problem: Using base 7 ONLY What is one half of 5? (Your answer X 2 should = 5) It can't be done normal...
