is this accepted? edit: JS based on @Ace's solution ///////// var neg = (num) => ~num + 1; for(var i = 0; i < 20; i++){ var num = Math.floor(Math.random()*999999999); console.log(`Original: ${num}\nNegative: ${neg(num)}\n`); } ////////// https://code.sololearn.com/c8J5t6j4PPcI/?ref=app

No literal minus sign but... https://code.sololearn.com/cgkhwg90141Q/?ref=app It follows the rules but it’s more a joke than anything else 😁

oops posted the wrong one, https://code.sololearn.com/WVzhIQ1ASV9h/?ref=app now it's okay I guess. But my code is similar with @Burey's one, and I am not sure how to do it on the other way...
