JavaScript Math object allows you to perform mathematical tasks on numbers. The Math object includes several mathematical methods. You use Math using dot operator and name of the method. Also JavaScript provides 8 mathematical constants that can be accessed with the Math object.

**Constants:**

- Math.E,
- Math.PI,
- Math.SQRT2,
- Math.SQRT1_2,
- Math.LN2,
- Math.LOG2E,
- Math.LOG10E

Notice all constants are using UPERCASE letters like in Level language.

**Methods:**

The method return a result that may be captured using assign operator “=”

var V = Math.max(10,11,12); // return 12
