• Addition (+) : document.write(a+b);
• Subtraction (-) : document.write(a-b);
• Multiplication (*) : document.write(a*b);
• Division (/) : document.write(a/b);
• Modulus (%) : document.write(a%b);

Addition Assignment operator: It is used to add new value to existing value.

Syntax  : var x=30;

x+=10;

document.write(x);

Output : 40

Subtraction Assignment Operator:  Subtract the new value from existing values.

Syntax : var x=30;

x-=10;

document.write(x);

Output: 10

Multiplication Assignment Operator: Multiply the new value in existing vale.

Syntax: var x=30;

x*=10;

document.write(x);

Output : 300

Division Assignment Operator: Divide the new value into existing value.

Syntax : var x=30;

x/=10;

document.write(x);

Output: 3

Modulus Assignment Operator:  It written remainder between existing value and new value.

Concatenation Operator(+): It is used to concat one number and one string data type or two string data types.

Syntax : var x=’30’;

var y=’20’;
