# Just another one...you don't need any in depth knowledge

## Question

Just exchanging components doesn't count. And by definition, one divided by zero is undefined.

Replace infinity with n and 0 with a. From the first one we have as n-> infinity a->0. 1/n=a so 1/a=n. In this case (equation is equivilent) as n->infinity a->0 so we have the second equation.

first replace infinity with a variable. Let's say x. Next write the equation with the x: 1/x=0 To even it out, multiply each side by x to get 1=0x Finally, divide each side by 0 to get 1/0=x

Noting that infinity is not an algebraic quantity like zero is,

I'm wondering if this is a picture puzzle and not a math puzzle?

1. Turn both sides of each equation sideways to get:

- 18 = 0

- 10 = 8

2. Add eight to both sides of the top equation.

Done.

I shouldn't be concerned. Puzzles with similarly goofy gimmicks get posted here all the time, and putting it in anything but the Math subforum would probably have given away the answer.

(And I'm hardly the one to talk, given that my solution to the "connect four towns with roads" problem was to make a "giant mile-wide road that covers the countryside.")

Right on both counts.

Nice puzzle Barcallica.
