Question

I need some help how to make this math formula in javascript. i have tried searching but couldn\'t really find cause i dont even know what ^ is called in English.

^ is the bitwise XOR operator - not what you want. Use the Math.pow function for exponentiation:

Math.floor( 20 * (Math.pow(1.1, x - 10)) );

Set this up in a function so you can use x for whatever value it may be:

var eq = function(x) {
    return Math.floor( 20 * (Math.pow(1.1, x - 10)) );
};
