RE: 1 × 0 = 0 BUT 1 ÷ 0 is undefined - school is the rule

in #school8 years ago

You are writing this comment using devices and complex infrastructures built with math. And it works, so I see no problems in undefined.
Did you ever divided anything by zero in real life? : )

Math is good. But the issue here is that the math doesn't apply anymore, where is multiplication there is division too.

I need a real-life example of division by zero to understand why a division by zero would not be undefined.

Exactly, reality becomes inconvenient at some point for science... If this happens to simple algebra then what about advance physics? If 1 × 0 has an result so should 1 ÷ 0. But not quite, the issue is mixing apples with pears, zero is not a number, zero = the undefined itself.
