Nicholas, you need to learn to express yourself properly.

This is your first line

7 + (10 − 4)2 ÷ 4 × 1/2    2       2 is a Numerical Expressions

The black numbers are fine and so is the writing at the end BUT  what  are the two red 2s supposed to mean?

I honestly do not understand.

Please let Nickolas answer this question.

Your question does not make sense Nickolas.

Perhaps you can fix it?

Thanks Alan.  :)

I do not doubt you Rom but how do you know that those are the only 2 quadruples?

Hi Chris,

I really like your idea of putting it in a semicircle!      

Derpy thinks that you mean     \(\sqrt7\)

And LagTho thinks that you mean   \((\sqrt7)^2\)

You could mean other things as well.   

You have not worded your question properly.  

Thanks guest. :)

Thanks Tiggsy.

I do wish you would get yourself an account.

I have often want to look back at your contributions and I can't.

If you had posted under username it would be easy for me to do.  

What about this statement Alan.

"Since xyz is positive, two of them aren't negative because a negative times a negative is a positive, and we've already ruled out the option of three."

If we had          a negative * a negative * a postitive then    xyz would be positive and that is what we want.

Say I said

\(sin\theta=-0.654\)

What quadrants would the answer be in?   What is the value of theta?  Is this an answer for a, b or c?

If you need more info then ask a specific question.

Please no one answer over the top of me
