Gary Duffala, a Rio Rancho, N.M., reader, regarding QT’s mention that zero is a number, writes:
“Zero is not a number. It’s a place holder. If zero were a number, then 0/0 would equal 1. No?”
QT has consulted with the faculty of the Northwestern University Department of Mathematics:
+ “Zero is a number. However, division is defined only when you divide by a non-zero number, hence 0/0 is not defined.”
+ “I don’t know of any mathematician claiming that zero is not a number, but in the end it depends on how you define ‘number.’ ”
QT consulted for a simple reason.
It knows squat about higher mathematics.
Squat being a number, also
