finicy and missing a lot of fetures like history also when you type you can only write numbers and not symbles. Another thing is when you type it types at the front of everything randomly making it anyyoing to delet things. Just dont waste your time with this extention

History, backspace and clamps missing.

grat one

nice and simple.

Great app overall, but you can't use your keyboard. You have to click on the buttons with your cursor.

Simples e Completo. Que o faz útil da melhor maneira... Ser Rápido e Exato!

Super prática! Eu realmente gosto da calculadora !

I would give it 5 stars if you could use parenthesis when calculating.
Even a simple calculator needs it.

Trying adding other modes like programming, scientific advanced etc.
