This was the most difficult of the three.

It is interesting that a complicated expression can be summed so simply.

Actually the backslash (\) should be a forward slash (/)

The 'hide' feature, and some others, are covered here.

You can also find out how someone did something or other just by clicking the "Quote" tab in the bottom right-hand corner of their post...but you must be logged in to see that tab.

Hi Denominator;

I have been backslashed again. Phrontister is right.

I think you are going to pull a math muscle. That can be painful. Do not forget to stretch before you do any more of them. Drink plenty of liquids too.

Hi bobbym,

Thanks for the advice.

For me, math is relaxing. I drink plenty of water, weather is very hot here!

Oh, is it, ok. I too haven't heard about it.

The nearest thing was a report from the old Soviet Union. They used to believe in "overexertion of brain cells."
