There are four basic functions in math. They are addition, subtraction, multiplication and division. Children in 1st grade focus on addition. They are required to memorize their addition facts from 1 to 12.

Create a function that prompts the user to enter a number between 1 and 12. Then display - using the input supplied - the addition and subtraction math facts for that number from 1 to 12 for the number entered. The output should be the results of the mathematical calculations.

See below example below:

The user enters "5" as their input. Below is the expected output.

Addition Math Facts for "5"

5 + 1 = 6

5 +2 = 7

...

5 + 11 = 16

5 + 12 = 17

Subtraction Math Facts for "5"

12 - 5 =

11 - 5 =

10 - 5 =

...

7 - 5 = 2

6 - 5 = 1

5 - 5 = 0

* Please note the subtraction facts should stop at the input number - the input number because 1st graders are not prepared to learn about negative numbers.

If the user enters a number not between 1 and 12, open an alert window stating that it is an invalid number, and prompt them to enter a number again meeting the criteria. Finally, if the number entered is bellow 6, make the background color blue and the text white, if the number is above 6 make the background color red and the text yellow, and if the number is six then make the background color white and the text black.

* Should be in HTML language.

HINT: use a variable and a window.prompt() to store what the person enters, a conditional statement, and string concatenation using HTML as we discussed in class.

Write a Python program that will perform various calculations (addition, subtraction, multiplication, division, and average). The program will add, subtract, multiply, or divide 2 numbers and provide the average of multiple numbers inputted from the user. You need to define a function named performCalculation which takes 1 parameter. The parameter will be the operation being performed (+,-,*,/). This function will perform the given prompt from the user for 2 numbers then perform the expected operation depending on the parameter that’s...

In Visual Studio in C#, you will create a simple calculator that performs addition, subtraction, multiplication, and division. Your program should request a numerical input from the user, followed by the operation to be performed, and the second number to complete the equation. The result should be displayed to the user after each equation is performed. For example, if the user performs 3+3, the program should display 6 as the result. The program should continue running so the user can...
