    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

[The Math Game] Get the left side of the equation equal right side using the numbers 1-9. It is easier if you know how to multiply.

u/sigveseb

Cool game! Only problem is when the goal number's prime decomposition contains a prime number with more than one digit (e.g. 11 and up). Then it is impossible to enter the correct answer!
u/MrM@_S

"3+3+1=7" so X*=s++%4*~~t%4+1 would never have a prime composition of 11 etc. I am pretty sure that my algorithm prevents such causes.....
u/MrM@_S

wait it is "(0-3)*(0 to 3)+1"
u/MrM@_S

(0 to 3)
u/MrM@_S

that leaves a 1 through 10 possibility
