Question about Canon F-502 Calculator
When I press on 8 or 9, nothing happens. Plus, when I use 4, 5, 6 or 7, the result is incorrect. I tried 7 x 6 and the result was 52. Then, I tried 6/5 and it came out as 1... And also, all the keys apart from the numbers aren't working (Pi, square root, parenthesis etc.) Q.Q
It appears your calculator is working perfectly well in octal. You should see a display indicator reading "OCT".
To switch to decimal, press 2ndF [-DEC] (-DEC is on the "+" key).
