In sequence to the initial thread where someone asked "why the answer of multiplying any number by zero always gives zero as the answer. I've always wanted to ask this question, maybe the mathematicians in the house can give me a clearer answer.

Why is it that when you divide 0(zero) by any number, it gives zero as the answer; but when you divide a number by zero , the answer is undefined, gives error or as some would say, "it's mathematically impossible"



FP please.

Division by zero means division by nothing which is meaningless or undefined.

In programming it is called fatal error!!
You can't divide a number by nothing

Alright Op to answer your question I would prove here that 1=2 following all mathematical rules except that a number can’t be divided by zero.
1=2


Let a=b - - - - - - - 1


Multiply both sides by a


a^2 = ab - - - - - - - - 2

Subtract b^2 from both sides


a^2 - b^2 = ab - b^2 - - - - - - - - - 3


Diff of two squares in L.S


(a-b)(a+b) = b(a-b) - - - - - - - - - - 4


Divide B.S by (a-b) - - - - - - - - - 5


(a+b) = b - - - - - - - - - 6


Since a = b

b + b = b

2b = b

2 = 1

The problem here is in step 5 because a = b meaning a - b = 0 which should automatically cut short that proof because by dividing by zero, their is a whole lot of shit you can get out of it. That is why it is always undefined.
