Re: Surds: Dividing by Negative NumbersOh okay, sorry for sounding rude ^^ What level do you teach at?(Original post by Mr M)
Wasn't ever unhappy. TenOfThem and I are maths teachers - GCSEs had not been invented when we were at school if that explains the dinosaur reference. -

Re: Surds: Dividing by Negative NumbersHey,
I've got another question about Surds... if you don't mind helping lol xD
7(sq root of 5) + 15 / 5, can you cancel down the 15 with the 5, to make it: 7(sq root of 5) + 3, or can you only do it when the whole thing is divisible by the denominator, in this case, including 7?
Cheers. -
