The InstantRide Driver Relationship team wants to learn how many travels each driver has done in the month of October. You need to send them the DRIVER_ID, and two calculated columns: DAY and RIDES. The DAY column is calculated using the DAY() function with the TRAVEL_START_TIME as the argument. The RIDES column is calculated by using the COUNT() function to determine the number of rides given for each day. Filter the results with the MONTH function.

In the main.asm file, you are to create a few arithmetic calculations using the following instructions: mov add sub Then after each expression is calculated, you will print the result using: mov rdi, XXX call print_num call print_lf The value of XXX will depend on which register your final result landed. Do this at least 3 times using only the registers ( rax, rbx, rcx and rdx). For example, if you wanted to print the result of 32 + 5 - 10, you could do something like: mov rax, 32 add rax, 5 sub rax, 10 mov rdi, rax call print_num call print_lf Remember that in order for the print_num subroutine to print your number, you must move the result into rdi.
