Day 7 - Exercise 1 : Calculator

Operators

These are symbols that used to join (generally) 2 or more operands and performs some action on those.

Arithmetic Operators

Operators	Description	Example
+	Addition	3+2
-	Subtraction	3-2
*	Multiplication	3*2
**	Exponentiation (ES2016)	3**2
/	Division	3/2
//	Floor Division	3//2
%	Modulus (Division Remainder)	3+2

a = 10
b = 3
print("a+b= ", a + b)
print("a-b= ", a - b)
print("a/b= ", a / b)
print("a*b= ", a * b)
print("a**b= ", a ** b)
print("a%b= ", a % b)

Exercise 1 - Create a Calculator

Create a calculator capable of performing addition, subtraction, multiplication and division operations on two numbers. Your program should format the output in a readable manner!

Solution

This includes some advace topics that are not covered in the lessons yet 😅. Sorry for that.

# a = int(input("Enter first number: "))
# b = int(input("Enter second number: "))
# o = input("Enter the operator: ")

# Hardcoded values
a = 4
b = 3
o = '+'

if(o=='+'):
    print("The addition of",a, 'and', b, "is", a+b)
elif(o=='-'):
    print("The subtraction of",a, 'and', b, "is", a-b)
elif(o=='*'):
    print("The multiplication of",a, 'and', b, "is", a*b)
elif(o=='/'):
    print("The division of",a, 'and', b, "is", a/b)
else:
    print("Operation not valid")
