    It would be 16. Because you have both multiplication and addition, you need to follow the order of BIDMAS
    Brackets
    Indicies
    Division
    Multiplication
    Addition
    Subtraction

    Becasue multiplation comes first in the order and you don't have BID (Brackets, indicies or division with this question) you do 4 x 2= 8 and then 8+8=16

    I see :lol:

    It's certainly challenging. I used to put in around 20 hours a week during term time (excluding lectures) and around twice that before exams

    lool, damnnn that must have been stressful would you say you had time doing other things in your free time? And how would you say the hours compared with other courses? And how long were lectures?

    sorry for bothering you, im just seriously considering a maths degree cos it seems so interesting at uni

    You may be tempted to try to solve this in excel (and it might well get the correct result - I've not tried) but one thing I do know that excel is wrong is the following:

    a^b^c

    Mathematically it should be computed as: a^(b^c)

    but excel does this: (a^b)^c

    You really have to love maths to do a degree in it because you'll be exposed to it 24/7 over 3 to 4 years.

    Plus the maths at school is only a small part. Even doing STEP does not prepare you for "proper" pure maths.

    (It's a pity group theory is no longer included in the A-Level syllabus).

    I really do love maths, one of the only things i enjoy tbh. I've done some research into the degree and im up for the challenge but the only thing thats putting me off is the number of hours, in manchester for example its 9-5

    1 lecture is around 50 mins long Yeah I still had a good amount of time to do other things (always saved a few hours every day to relax and do other stuff) but that wasn't so easy around exam time. I think it's the same for pretty much all courses apart from Medicine (more contact hours but not as hard as Maths/Physics )

    Ooh I'd certainly recommend it! :yep: But you have to have a real interest in the subject to do it at uni

    Yeah if you do very well at AS level then you'll be in a very good position

    I'm not at Cambridge yet (starting later on this year) but I'm going to be doing Part III which is a year long postgrad qualification in Mathematics. After that I'm thinking of doing a PhD but maybe not. Depends on what I like the look of
