Calculation, wrong result

I would like to report a ChatGPT bug. When entering a long math example, it repeatedly gives wrong results. The correct result is 162160, but every time the program tries to calculate the example, it comes up with a different result.
Konkrétně jde o příklad 137002+20002+3000+5002+(3000+2000+700)2+56802+12003+22002+50024+2000+3000+1000+1500+1700+30003+5006+6002+800+900+40003+60002+50011+60002+15002+1000+5004+21004+500*8
