# Javascript Multiplication( * ) & Division( / )

The multiplication operator (*) perform arithmetic multiplication on numbers (literals or variables).

console.log( 3 * 5);
console.log(-3 * 5);
console.log( 3 * -5);
console.log(-3 * -5);

15
-15
-15
15

### Division ( / )

The division operator (/) perform arithmetic division on numbers (literals or variables).

console.log(15 / 3);
console.log(15 / 4);

5
3.75

### Decrementing (--)

The decrement operator (--) decrements numbers by one.

• If used as a postfix to n, the operator returns the current n and then assigns the decremented the value.
• If used as a prefix to n, the operator assigns the decremented n and then returns the changed value.

• var a = 5, // 5
b = a--, // 5
c = a // 4

### Output

In this case, b is set to the initial value of a. So, b will be 5, and c will be 4

var a = 5, // 5
b = --a, // 4
c = a // 4

### Output

In this case, b is set to the new value of a. So, b will be 4, and c will be 4.
