Calculator Zero

Bare bones calculator
Calculating from previous result instead of going with calculation order
For example normally you should have 1 + 2 * 4 = 9
Cause all calculators would go with 2 * 4 = 8 first and then 1 + 8 and you would get 9
My calculator is going 1 + 2 * 4 = 12
Cause 1st it calculated 1+2=3 then 3*4 = 12
I just needed it cause all calculators i found had too many buttons i could not hide
While i did not like their design

Decimal characters are limited to 2nd digit after dot
If you wanna see full decimal hit = equal button
