Supposing you said that

n / 0 = k

where n and k both did not equal 0. Then we could multiply by 0 on both sides.

n = 0 * k

n = 0

something is wrong I just said n and k did not equal 0. Dividing by 0 leads to lots of contradicions.

hi branster707

Welcome to the forum.

a/b-c = a/b - a/c

1/(1-1) = 1/1 - 1/1

You have a bracket in line 2 that is missing in line 1.

Either way, the algebra is wrong. Suppose a = 7, b = 5 and c = 3

whereas

If you put in the bracket:

So your theory falls at line 1. Sorry.

Division is defined as the inverse process to multiplication. Thus:

So, in order to find a meaning for

we must look at this multiplication:

This equation has no solution, so you cannot find a meaning for dividing by zero. (unless you are prepared to abandon either the definition of division or the properties of multiplication.)
