Bug in the calculator S20 FE 5G

[ashishanaredy]

When you want to start by typing a negative number the calculator throws an error "Invalid format used"

Eg: It does not allow me to calculate "-5+2" as soon as I type "-" it gives error

It happens in my mobile too. F62.
Its not bug maybe.
Its not technical calculator. So this issue is coming.
If you are engineer or have huge heavy technical task, you must buy technical calculator. That will give you correct result.

Try Using +/- tab instead
