Calculator topics

In my project of a React calculator, i actually can make it do 5.5.5 to display 5.55 and 10.5 - 5.5 is really 5. But in the run test menu still gives me an error… Help plz.

the codepen link is: Calculator (codepen.io)

Try doing 5.5.5 then clear it (AC) and do 5.5.5 again.

Also, when I run the test I see NaN at one point which would suggest some math operation on invalid values.

thanks, i wasn’t refreshing all the state when ac was pressed.
now i can not handle two consecutive signs like this: 5*-2, if you could help… :slight_smile:
