    I should have done maths degree , some of the elec engineering subjects I do are kinda hard , but maths is just maths , reckon I could have got better marks at it. Only problem is that a maths degree is kinda useless for getting a job, plus it would get boring after a while

    \[log_2 \frac{4}{8} = log_2 4 - log_2 8 = log_2 2^2 - log_2 2^3 = 2-3 = -1 \] Is another way you can solve it.

    it would be easier for a engineer to swap with a mathematician, than it would for a mathematician to swap with an engineer. For starters engineering involves group work and gets quite stressful at times, whereas maths is all independant

    uyeh, but you dont need a maths degree to deal with ratios on a recipe :p see what I am talking about , most of the practical ( and therefore , useful ) maths is taught in high school and first or second year maths ( the stuff that engineers do ). Higher maths is sorta useless
