my teacher asked this but i dont know why you cant divide by zero

1)Let us try to use a nonzero number divided by 0 . For example, 5 divided by 0: 5/0=? so 0*?=5 Since any number multiplied by 0 equals to 0. Hence, there is no number that solves the equation. Hence, the value of a nonzero number divided by 0 remains undefined.

2)Let us try to do 0 divided by 0 . 0/0=? so 0*?=0, Any number multiplied by 0 equals to 0, so ? can be any number. Hence, the value of 0 divided by 0 is still undefined.

While zero shows up at the end of 10, 20, 30..etc it has a value there. But zero alone is not a true number..in my opinion because zero is the absence of value. Alone its not a number but the absence of a number and a place holder on the number line.

Rich, are you saying zero is not a number? I strongly disagree. Not only is zero a number, it is one of the most important numbers, perhaps THE most important.

zero is the answer to the sum of a number and its additive inverse. In other words, the definition of an additive inverse is a + (-a) = 0

I wish you could "like" these comments, because if I could, I would "like" Robert's.

Gady, you teacher asks a good question. Imagine, if you decide to give something that you separate easily. Got that? Now let's say there were it could be split into parts where where each person got one. This makes sense when you are dealing with whole persons right. But it does not make sense when there are zero persons. This is what Math teachers will call undefined. Take for example

Well you can't give any portion sense you don't know what portion to give for zero and it can't be the whole thing or a portion of it, so they determined long ago to agree this is undefined (not define).

So if anyone asks, what do you get when you divide by zero, just say the Math people said it is undefined or not defined. They will say back, that is good or

I could never do it either. Tai (the Math guy)
