Answer 2

but it works😳 silent, where I forgot one eval?

Answer 3

var equation = new Array(8, "*", 2);

var multiply = 0;

var eqLength = equation.length;

for(var i = 0; i < eqLength; i++) {
multiply += equation[i];
}

document.write(eval(multiply));

Brains solution is more simple of course. But, if we change the array...

Answer 4

eval(eval(eval("(function(num) { return eval(Math.sqrt(num)) })(225)")))

is it correct, guys? help

Answer 5

@4rontender nope. you've forgot one eval.

Answer 6

-> eval( <- eval(eval(eval("(function(num) { return eval(Math.sqrt(num)) })(225)"))) -> ) <-

Answer 7

eval("equation[0]+equation[1]+ equation[2]");
might work

Answer 8

Thank you all

Answer 9
