Problem - double two triple one

Can anyone give me some hint about this problem ?

My code… What I have tried so far :-

function doubleTwoTripleOne(one, two, three, four) {
    let sum = 0;
    if ((one*2) && (two*2) && (three*3) && (four+4)) {
        sum = sum + one + two + three + four;

Why do you have an if statement? If for example one will be zero, operation inside if won’t run.

Why did you add an if statement? Can you describe your code in English?
