Students will learn how to perform simple calculations using fixed numbers, numbers in variables, and numbers from the user

Be able to read, understand, trace, adapt and create Python code using selection that:

• Perform simple operations such as addition (+), subtraction (-), multiplication (*), and division (/) on fixed numbers
• Perform simple operations on numbers stored in variables
• Convert strings into integers
• Gets number input from user and use it within calculations

If one / is used for division, the result will be a decimal, known as a float. If two // are used for division, the result will be a whole number, known as an integer (or int for short).

Input from the user in Python code is usually a string(text), but calculations required an integer(whole number) or a float(decimal number). Casting is the act of changing the data type of a variable to match a need.

To save the user’s inputted number as a whole number in a variable, use **int(input(“Ask user to enter something -> “))

To save the variable as a decimal number, use **float(input(“Ask user to enter something -> “))

When you run into an error with your code, ensure you have checked the following:

• The variable name you have declared is the exact same throughout the program
• You have used a single = to assign variables
• You have used the correct operators for:

  • + addition
    

  • - subtraction
    

  • * multiplication
    

  • / float division
    

  • // integer division
    

• You have placed brackets around input()
