Hi! Is there a way to make a calculator from scratch using Velo? Something like what Google uses ( Google Calculator ), but somewhat simplified with function.

Before you start to code somethin like that…

First make sure you are able to understand RETURN-FUNCTIONS.

Okay!

After we do that, what do we do?

After you have understood return-functions → you start to code some of them.

Which functions/operations is a calculator able to manage? Let us pick-up the most simple ones…

  1. addition
  2. substraction
  3. multiplication
  4. Division

Of course there are much more operations and functios, but start first with simple programming.
Ok, let’s generate a simple addition-return-function.

What will this function be able to do?
The function will be able to generate a sum of 2 numbers, sum them together.

function addition(a, b){
return(a+b)
}

So, now you generate to variables (x,y) or (a,b) or which ever you want, and give them a VALUE…

let x=33;
let y = 44;

Now you start your -->ADDITION-function with a click onto a ±button.

$w.onReady(()=>{
  $w('#myPlusButton').onClick((){
    addition(x,y)
    // or directly....
     addition(33, 44)
  });
});

What do you get as RESULT?
