It is a mathematical term. Do you like Surds? can you understand them?
I had a Maths exam today, and the most eviliest Surds questioned was waiting for me at the end of the paper. It was the Surface area of something, so width x height x depth, and you had to leave your answer as a√2 with a being an interger. It was bloody awful.
I had √2 x √4 x √1/2. It was the fraction that threw me.
an example of Surds:
(1 + √3) × (2 - √8)
= 2 - √8 + 2√3 - √24
= 2 - 2√2 + 2√3 - 2√6
Ever get left nasty exam questions at the end of the paper? or any nasty ones at all?
Another nasty one was doing forumulas ;_;
P = kh or something like that. One of those came up too
