Answer
$2965 = MMCMLXV$
Work Step by Step
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,
$\\2965 = 2000 + (1000-100) + 50 + 10 + 5
\\2965 = MMCMLXV$
