The Mathematical Curiosity of 1881

The year 1881, says an exchange, will be a mathematical curiosity. From left to right and from right to left it reads the same; 18 divided by 2 gives 9 a quotient; 81 divided by 9 gives 9; if divided by 9 the quotient contains an 8; if multiplied by 9 the product contains two 9s; 1 and 8 are 9, 8 and 1 are 9. If the 18 be placed under the 81 and added the sum is 99. If the figures be added thus, 1, 8, 8, 1, it will give 18. Reading from left to right it is 18, and reading from right to left it is 18, and 18 is two-ninths of 81. By adding, dividing and multiplying 19 9s are produced, being one 9 for each year required to complete the century.
