after you netcat, a program greets you and asks you to answer 9 math questions to get the flag.
the first 8 questions are easy ans simple.
the ninth question is 0.1 + 0.2.
this does not equel 0.3 because of [floating point math](https://0.30000000000000004.com) and so its equal to 0.30000000000000004.
after the ninth question the flag is printed.
