@kshitiz i will rename the variable so it is human friendly var x, xx, y, z, xxx = parseInt(document.getElementById('ANID').value, 10); /* user input because variable xxx take input from user (datatype is string even if you type in a number) then convert it to integer. */ x = (xxx == xxx); // variable x is true (remember boolean) x = (++x*x*x+x); /* since x is true than its value is 1 so (++1*2*2+2) is 10 ++1 is 2 (preincrement) */ xx= (xxx%x)*(xxx%x); y = (x/x)+(x/x); z = (x/y); y = (y*y*y); z = (z*z*z); y = (y*y*y); z = (z*z*z); x = y*z - xx/xx; if ((xx*xxx) == x){ alert("Yes, You are right !!!") } else { alert("Miouwww,Try again!") } }

Answer will be 8 digit number and the last digit is (Input % 10). And the equation was : input * ((input % 10) ^ 2) = 999,999,999 so, input = 999,999,999 / (last digit of the input ^ 2) On my calculator I entered 999,999,999 / (9 * 9) and it showed 12345679. Was right in first guess.

@Cyrus You may want to hide your equation. It's correct now. @Sachin hid his 😀 p.s. the calculation is surprisingly easy. Don't overthink it 👍
