LU07.A09 - Basic caluclator simple

• Work type: Individual
• Means of aid: only teaching materials, no websearch, no use of ai.
• Timeframe: 45 Minutes
• Expected result: A browser based calulator which can sum up 2 digits in the easiest way.

• You can take any script an adjust it to your needs.

This assignment compraises the programming of a tiny caculator for basic calculation operations, meaning two diggit have to be added together. To do the assignment we need two blocks of diggits-buttons, an operation-button for „+“ and finally an ENTER-Button to execute the operation respectively to receive the result.

• A01: Create in Webstorm in your directory 07_methods a html file and name it correctly LU07.S09.
• A02: Copy the structure of the sfc (single file component) from a solution of your choice (in that way we don't have to type it manually –> easier and faster)
• A03: Make sure to have
  • the assignmen number in <h1> and
  • the description in <h3>-format
• A04: Safe it.

• B01: Create the buttons 1 to 4 (that shall suffice for our purpose)
• B02: When clicking on one of them the content will be saved in the variable diggit1

• C01: A basic calculation 3 + 3 = 6 compraises several variables and their initial values:
  • diggit1: 0
  • operator: ''
  • diggit2: 0
  • result: 0

• D01: Create the second set of buttons 1 to 4 to set the second diggit. (4 of them shall suffice for our purpose)
• D02: When clicking on one of them the content will be saved in the variable diggit2

• E01: To execute our addition-operation we finally need a button ENTER.
• E02: This enter calls a method calcResult(operator).
• E03: Thus the addition is done in the method, correspondingly to the providet operator.
• E04: As a result, after pressing the enter button, the result should be displayed in the screen.
