What is the wrong step???

0 = 0
1.0 = 0
1 = 0/0
1 = undefined..

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

At the second to third step. You assume that the equation becomes, at LHS,

$1 * \frac{0}{0}=1$

which aren't true.

The basic algebra rule that both lhs and rhs are divided by 0.... see in algebra, we may divide things from lhs to rhs, but the basics are that, we dont actually take that number from lhs to rhs.... but divide both the lhs and rhs by the number, so dividing by zero will be impossible.....as you divide both lhs and rhs by zero, then it becomes 1.(0/0) = (0/0), where one of the (0/0) is considered as 1 by you in the third step and the other as undefined.......if u still dont understand, i will try to elaborate and send u a link later (which am not sending now cause am too lousy to search for it)...
