I am trying to make a code that just is an math calculator in serial monitor here is answer in serial monitor
Sketch uses 6352 bytes (19%) of program storage space. Maximum is 32256 bytes.
Global variables use 552 bytes (26%) of dynamic memory, leaving 1496 bytes for local variables. Maximum is 2048 bytes.

avrdude done. Thank you.
Ok

if (valid) {

Serial.println(result);

}
can it work as a calculator not just text
I am using uno with port com3
