====== LU06.S08 - Events - basic calculator ======
===== Assignment =====
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 and a operation-button "+" to execute the operation respectively to receive the result.
==== Assignment A - 3' =====
* A01: Create in Webstorm in your directory **06_methods** a html file and name it correctly **LU06.S08**.
* 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 assignment number
-titel and
* the description in -format
* A04: Safe it.
==== Assignment B - Variables - 5' ====
* B01: To make an addition work in our VUE instance we need threee variables with the corresponding initial values
* diggit1:0
* diggit2:0
* result:0
==== Assignment C - Button for diggit 1 - 10' ====
* C01: Create the buttons 1 to 4 (that shall suffice for our purpose)
* C02: When clicking on one of them the content will be saved in the variable **diggit1** with the corresponding number 1-4, meaning when clicking the 1, the variable diggit will be set with 1.
==== Assignment D - Button for diggit 2 - 2' ====
* 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**
==== Assignment E: Implementation of the calculation - 10' ====
* E01: To execute our addition-operation we finally need a button **Operator**-button.
* E02: Clicking this operator-Button adds diggit1 to diggit2 and displays the result (result = diggit1 + diggit2)
==== Assignment F: Reset button - 5' ====
* F01: Create finally a **reset**-button which sets all value to the initial ones.
* F02: Meaning clicking on the reset-button uses: result=0, diggit1=0, diggit2=0
