Introduction
Math is a built-in object that provides properties and methods for mathematical constants and functions to execute mathematical operations.
Unlike many other global objects, the Math object has no constructor.

1⃣ Math.abs
The "Math.abs" function returns the absolute value of a number. It takes a number as its parameter and returns its absolute value.
{ 3 / 13 }
The "Math.abs" function returns the absolute value of a number. It takes a number as its parameter and returns its absolute value.
{ 3 / 13 }
2⃣ Math.ceil
The Math.ceil function always rounds a number up to the next largest integer. It takes a number as its parameter and returns its upward round value.
{ 4 / 13 }
The Math.ceil function always rounds a number up to the next largest integer. It takes a number as its parameter and returns its upward round value.
{ 4 / 13 }
3⃣ Math.floor
The Math.floor function rounds a number down to its nearest integer. It takes a number as its parameter and returns its downward round value.
{ 5 / 13 }
The Math.floor function rounds a number down to its nearest integer. It takes a number as its parameter and returns its downward round value.
{ 5 / 13 }
4⃣ Math.round
