Alim Niyazov , first you don't need to print with specific values =>console.log(convert(100, 1.1). Replace semicolons with commas between the function parameters and arguments. You can't say return = a * b. Instead write return a * b
try this way :
function main() {
var amount = parseFloat(readLine(), 10);
var rate = parseFloat(readLine(), 10);
console.log(convert(amount, rate));
}
function convert(a,b){
return a*b;
}
