What is LXIX in Hindu-Arabic numerals?

Answer 1

LXIX is 69

L = 50

X = 10

I = 1

In Roman numerals, the largest value goes to the left, followed by the lesser values to the right. Except when a smaller value is placed before a larger value it means subtract the smaller value from the larger value to the right.

Hence

LXIX

= 50 + 10 + ( 10 - 1) = 50 + 10 + 9 = 69 .

Answer 2

69
