Write a program that prompts the user to enter an equation in the form of 10 5, or 10-5, or 1*5, or 13/4, or 13%4. The program should then output the equation, followed by an equal sign, and followed by the answer.

Answer:

  1. equation = input("Enter an equation: ")
  3. if("+" in equation):
  4.    operands = equation.split("+")
  5.    result = int(operands [0]) + int(operands[1])
  6.    print(operands[0] + "+" + operands[1] + "=" + str(result))
  7. elif("-" in equation):
  8.    operands = equation.split("-")
  9.    result= int(operands [0]) - int(operands[1])
  10.    print(operands[0] + "-" + operands[1] + "=" + str(result))  
  11. elif("*" in equation):
  12.    operands = equation.split("*")
  13.    result = int(operands [0]) * int(operands[1])
  14.    print(operands[0] + "*" + operands[1] + "=" + str(result))  
  15. elif("/" in equation):
  16.    operands = equation.split("/")
  17.    result = int(operands [0]) / int(operands[1])
  18.    print(operands[0] + "/" + operands[1] + "=" + str(result))  
  19. elif("%" in equation):
  20.    operands = equation.split("%")
  21.    result = int(operands [0]) % int(operands[1])
  22.    print(operands[0] + "%" + operands[1] + "=" + str(result))

Explanation:

The solution code is written in Python 3.

Firstly prompt user to enter an equation using input function (Line 1).

Create if-else if statements to check if operator "+", "-", "*", "/" and "%" exist in the input equation. If "+" is found (Line 3), use split method to get the individual operands from the equation by using "+" as separator (Line 5). Output the equation as required by the question using string concatenation method (Line 6).  The similar process is repeated for the rest of else if blocks (Line 7 - 22).
