I never studied Algebra, never took an interest in Maths in school, I was more about Science and hands on hardware, but i've just been accepted to enroll at my school and they're going to be testing my maths skills - eek, so I thought i'd quickly brush up on the basics of Algebra just incase i get asked about it.
So I find the video... basics on Algebra
X + 4 = 12
So this is the first example i'm confronted with... um i'm taken back what's the value of x? Surely the compiler will know that at compile time, who cares!
Then i thought, if i saw that in Code, how would i normally work that out? i'd go x = 12 - 4 (x must be 8 then)
he comes up with
x + 4 = 12 x + 4 - 4 = 12 - 4 x = 8
As far as i'm concerned, if i coded like this with a Micro controller i'm going to run out of variables fast so the question how does Algebra affect the programming world, as coders are we already not doing a subtle form Algebra anyway? every time i code a routine which involves numbers, is that not Algebra? i'm confused what's the relationship between coding what's it mostly represent in the mathematics world? because as far as I'm concerned, that guy's a moron, X is a variable so what is x REALLY?
is it an Integer? Float? see my point, maybe Algebra is simply a memory consuming monster Variant and X, Y can be what they want... int x,y,z; x = 10; x = x * 10; what's in X? again THE COMPILE DOES! but, X is 10 before it executes the line x = x * 10; now it's 100, in X, but as a programmer, this comes naturally to me to determine the value of a given variable well i Lie, i don't the compiler does lol... but I'd work it out through logic, can I not apply this to pure Algebra?
