Calculator with HTML, SCSS, JS and Mobile First.

I also noticed some things.

It does not let you do two signs at once, like you can't add and multiply at once, so that takes out the functionality of dealing with two negative numbers, and I think the dot should be restricted to only one entry if one were to attempt to click a bunch of them one after the other.

btw, looks and works good nonetheless.

Looks good

I did see 2 things:

One on desktop size the button did not become as wide as the design but without the design sketch file that would be hard to know

second the logic has problem with non whole numbers example 0.5 + 0.5 = 5.5
