Yes, sounds like a home-work problem.

The ST-LINK VCP for the NUCLEO board should be enough to talk back-and-forth with the STM32 USART. As I recall USART2 via PA2/PA3, but check the manual/schematic.

Enough for what?

What are you doing?

Debugging could use the PB3 TDO/SWO​ debug communication channel.

Actually the MCU should receive two numbers via terminal software(e.g. hterm) and give back the result (using USART USB). Moreover in the code should be defined a threshold value and the MCU should give back whether the result is higher or lower than threshold. The LED should ON if it is high and OFF if it is low.
