1. ## false equation

"x+3=x ; -x+x+3=-x+x; 3=0 In example we get a false equation."

Algebra and Trigonometry by Keedy/Bittinger.

False have lots of meaning which one in the link does "false" fit in "false equation"?

Thank you.

2. ## Re: false equation

"x+3=x" is not a correct equation. There is no number, x, that you can add 3 to and get the same number.

3. ## Re: false equation

A "false equation" is a very common term. From respect of language it might be seem incorrect but science also might have its own language. Here is an another example and there are lots of.

Thank you.

4. ## Re: false equation

Time dilation is too difficult to for a beginner, man. hhtt21, if you want to use "false equation", go ahead and use it. People say "jumbo shrimp" all the time so I'm sure "false equation" is nothing in comparison.

'False equation' is fine and natural. 'Equation' means

c Mathematics A statement asserting the equality of two expressions, usually written as a linear array of symbols that are separated into left and right sides and joined by an equal sign.

An equation asserts the equality of two expressions. It can be as false as the assertion that Moscow is the capital of France.

In example doesn't work either.

From this I have concluded a result that Americans and Brits think differently on this issue so this might be a difference between AmE and BE.

Thank you.

I think that is a false conclusion.

In both American and British English, an equation is an assertion which can be either true or false.

9. ## Re: false equation

We have plenty of false conclusions in the UK.

Because I want to learn good English.

Thank you.
