What is 1970 in roman numerals?

Answer 1

MCMLXXII equals 1972 M=1000 CM = 100-1000 L=50 XX=20 II=2 Simple Consideration: M:1000 D:500 C:100 L:50 X:10 V:5 I:1 www.gprsoft.com Another contributor's answer:MDCCCCLXX (1000+500+400+50+20) = 1970 CMMLXX (-100+2000+50+20) = 1970 LMMXX (-50+2000+20) = 1970 All of the above notations are acceptable but LMMXX is more preferable because fewer numerals are used. Note that contrary to popular belief 1970 in Roman numerals is not MCMLXX because the positional place value of some of these numerals are incorrect. Answer Unfortunately although LMMXX may be the shortest form of writing 1970 it breaks the rules of writing Roman numerals according to the website Algebra.com, which states that "L can preceed C but not D or M." MDCCCCLXX is numerically correct but is a very long winded way of writing MCMLXX and for this reason it is not commonly used. Roman numerals read from left to right with the largest number first. Therefore 900 + 1000 + 50 + 10 + 10, which is CMMLXX is just plain wrong. 1000 + 900 + 50 + 10 + 10, which is MCMLXX is the accepted way of writting 1970.
