$2965 = MMCMLXV$
RECALL: $M=1000 \\C=100 \\L=50 \\X=10 \\V=5$ When a smaller numeral is written before a bigger numeral, the value of the smaller is subtracted to the value of the bigger numeral. Note that: $2965 = 2000 + 900 + 60+5 \\2965 = 2000 + (1000-100) + 50 + 10 + 5$ Thus, $\\2965 = 2000 + (1000-100) + 50 + 10 + 5 \\2965 = MMCMLXV$
