Hi Kjetil-Lennart. JavaScript Math object allows you to perform mathematical tasks on numbers. Below I have list a few examples they are many more.

`Math.random() returns a random number between 0 (inclusive), and 1 (exclusive): Math.random(); // returns a random number

Math.round() Math.round(x) returns the value of x rounded to its nearest integer: Example Math.round(4.7); // returns 5 Math.round(4.4); // returns 4

Math.ceil() Math.ceil(x) returns the value of x rounded up to its nearest integer: Example Math.ceil(4.4); // returns 5

Math.floor() Math.floor(x) returns the value of x rounded down to its nearest integer: Example Math.floor(4.7); // returns 4

Thank you very much for your answer, these i knew, but! But i don't get the actual math there, i know it had something to do with finding the range between the number and such, but i can't get my head around how it works. You are very kind to take the time to answer
