Question

give an example of an undefined term and explain why it is undefined

Answer 1

\[\frac{ x }{ 0 }\] where x= any number
because there is nothing that can be over 0
Consider something like a pizza, you can have 1/2 slice (1 slice out of a 2 slice pizza)
but you can't have 2 slices of pizza from a 0 pizza.

Answer 2

thank you

Answer 3

Answer 4

Algebra? or geometry?

Answer 5

geometry

Answer 6

However, on the subject of division by zero: Think of the question that division asks, "how many times can this number fit into this other number?" Well, how much of nothing can you fit into something? Answer: as much as you want because nothing has no size, so there is no single unique answer, so it is undefined.

But that is an example of an undefined number.

An undefined term could be a word that is simply hard to define in any precise sense.

Answer 10

Oh nevermind, yes, with geometry, a point would be an example because it has no length, width, thickness, etc, it is not formally 'defined'.
