Having fun with numbers

Seriously Stirlo, your solution was a little bit messy at the end and your 4 doesn’t look like 4. Good maths is also about good presentation. Please do not think that I am being picky here, it is for your own good.

...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"

The things you need to know in life are:
sin, cos & tan relationships
sin & cosine rules
quadratic solution
& with Napier's rules you can find your way around the world.

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
Maths and chemistry were GOOD
Physics was interesting

Depending on how WRONG the experiment went

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

Bonus point for you, m'boy.
