0 = 1? Can you spot the mistake?

-20 = -20 16-36 = 25-45 4^2 - 4.9 = 5^2 - 5.9 4^2 - 4.9 + 81/4 = 5^2 - 5.9 + 81/4 4^2 - 2.4.9/2 + (9/2)^ 2= 5^2 - 2.5 . 9/2 + (9/2)^2 (4-9/2)^2 = (5-9/2)^2 4-9/2 = 5-9/2 4 = 5 0 = 1

1.) to every number n assign number 2n -1 so every number has an odd partner

there are as many odd numbers as numbers right or wrong?

➡ Spot on. So you are establishing a one one correspondence between the set of integers and set of odd numbers. Then, each point in the number line denotes a rational number. Doesn't it?

Yes the mistake is in the 3rd line from the last. You have to use ± if you Square root both sides. If you do not use ±, the following problem arise: (-4)²=(4)² or, 4 = - 4. But, this is wrong. So we have to use ± in front of both sides. ±4=±(-4).

Let me give you another problem: S= 1 + 1 + 1 + 1 +1 +... 0 + S= 0 + 1 + 1 +1 + 1 +... ------------------------------------------- (-) 0 = 1 + 0 + 0 + 0 + 0 0 = 1. Where is the mistake?

Wrong. Since there is a thing called cardinality. Are the no. of primes equal to no. of natural numbers? Are the no of points in a straight line equal to number of rational numbers?

For a new customer, he has to move old customers one room ahead. For example, consider a new customer comes in. And, then the hotel manager moves the customer in room 1 to 2, 2 to 3...goes on...

@Elvin Auresius: You've deleted your question querying help for your website, without any effort to be helped, and almost without respect for people taking time to study your case and answer you: << After completed html and css course i tried to make my own website, my website look perfect in my 1366,768 resolution screen, but everything messed up when i tried to open in different device or with differ resolution. They said i need to use % instead of px to make the elements exactly fit with the page according to the percentage, so i tried that. But the result was bad & i can't fully control everything in my web. Any suggestion about this issue? thx >> So, you will never see my quite working solutions (only css adapted to make the page responsive, and both html+css improved), as you doesn't deserve them ^^ (pretty good news: if I've done it you could do it :P)

@visph thx you still replying about that, honestly i can't fully understand your explanation, but people out there giving me detailed answer and helped me a lot in another forum, i completely recreate a new website with html + css, with completely different structure to prevent the website resizing by its own. After you said that the website is JUST A TEMPLATE and you reject the website is completely made by me with html and css, that made me feel hopeless to keep the question floating in the forum, because people will also alleging me that the website i created with completely my HARD WORK as a TEMPLATED website but thx anyway taking ur time and everyone that answering me. p.s: sorry for what happened in the past & thanks to try solve the problem
