...and be careful that your square root sign encompasses what you want it to.

For bonus points, does the 'root' sign have a one-word name? If so, what is it?

well...the 'root' sign is made up of a 'tick' and a viniculum.

after a bit of research on wikipedia i have concluded that the 'tick' is called the "radical"

Also...
simultaneous equations
Check your calcs

For 4 of my 5 years at high school, my maths teachers were WII bomber navigators, they thought checking the calcs was important, & used to get upset when we said '...but I had the correct method'.

Couldn't resist the temptation; Google came to the rescue, and found this: http://www.bbc.co.uk/dna/h2g2/A827453

In the first paragraph of Step One: "radical," which I'd forgotten until now. Nice refresher on extracting square root without a computer, too.

G'Day Joe,
I actually learnt this at school.
Trouble is, I kept forgetting to double the progressive answer.

Stirlo,
I know what you mean:2tsup:
Maths and chemistry were GOOD
Physics was interesting:cool:

Depending on how WRONG the experiment went:rolleyes::oo::doh:

Thanks Joe, you've refreshed my memory, I knew that once.
Also learned that method of extracting square roots at school.
