Explanation for Remainder Of Division

Let's start with a program that prints rectangle's area by knowing it's width and height.

width = 2 height = 3 # Calc Area: area = width * height print("Area =", area)

Output:

Area = 6

Explanation

• At line 5 width and height are multiplied (via * operator).

Let's demonstrate the rest of the operators:

a = 5 b = 2 print("A =", a) print("B =", b) print("A + B =", a + b) print("A - B =", a - b) print("A * B =", a * b) print("Remainder of Division:", a % b) print("Concating strings:") str1 = "Web " str2 = "Technologies" print(str1 + str2) numericStr1 = "1" numericStr2 = "2" print("1 + 2 =", numericStr1 + numericStr2)

Output:

A = 5 B = 2 A + B = 7 A - B = 3 A * B = 10 Remainder of Division:1 Concat strings: Web Technologies 1 + 2 = 12
