Help please from brainboxes of HUKD.
I have a tenner riding on this with my better half.

Thanks for the help.

210 is my answer too, worked it out before opening the thread so I didn't see the other two.

(6x5)x7=210

Why the brackets?

im guessing the fact that he is liking the 210 answers, he must be that one

Childishly I just wanted someone to say no it isn't

I'm not sure what answer there is apart from 210?

Why the brackets?

Putting something in brackets means you do that problem first. So (6x5)x7 means you do 6x5 first, which = 30. Then you multiply 30 by 7, which = 210.

couldn't 6xy also be 657??

They are 3 multiplications, so brackets would have no effect on which you solved first as they all have the same priority.

What else could it be?!

wow....lame maths skills if u had to bet on the answer to a simple equation a 7 year old could do!

As a poster said, it could also be 657.

I was right. Wife had (6x5) + (6x7) = 72. Primary school teacher as well!

Erm, not if its algebra it couldn't.

That would be 6(x+y), and that is pretty worrying.
