HOW TO DECLARE VARIABLE IN RUBY PROGRAMMING LANGUAGE

You can manipulate variables in exactly the same way that you would manipulate the objects that they represent.

'''Ruby Gem

>>var1=7 =>7 >>var2=4''' =>4

>>var3 = var1 + var 2 =>11

>>var = "hello" => "hello" >> var4 = var4 * var2''' => hellohellohellohellohello

>> num1 = 2 + 4 + 6 + 8 => 20 >> num1 = num1/5 => 24 >> num2 = num2 - num1 =>20

num1 = num1 / 5 num2 = num2 - num1 These kinds of expressions are very common, so Ruby offers you some shortcuts:

Example	Shortcut	Meaning var = var + 2	var += 2	Add 2 to var var = var - 3	var -= 3	Subtract 3 from var var = var * 6	var *= 6	Multiply var by 6 var = var / 2	var /= 2	Divide var by 2 var = var** 3	var **=3	Cube var var = var % 4	var %= 4	var modulo 4'''
