Put this into a number sentence (equation) for me please

10 more than a number 6 is 16.

You have to use the 10 the 6 and the 16 and what symbol would you use for "more than" when it is in a sentence like this?

Now do exactly the same thing with your question :)

now solve your equation.  

Hint your answer might be a negative number. 

Is 100^500 bigger or 1000^300?

\(100^{500} \\ or\\ 1000^{300} =(100^{10})^{300} = 100^{3000}\)

Can you tell me which is bigger now?

So you do not have a general purpose email account?

Can't you make one on another computer?

Just use your mums one maybe. Or ask her (or someone else) to make one for you.  ;/

There is an invisible × between the 8 and the h

The opposite of multiply is divide.

Divide both sides by 8 :)

Sure is :D

You cannot write it exactly with digits but you can get an approximation from any calculator.

Do you know how to factorise quadratics Hayley?

Anyway why dont you join ip?  We'd like you to   

That is a perfect square. What are we meant to be checking ?
