When Tom Larkins challenged his sisters to prove on a blackboard that if 50 is subtracted from the sum of the nine digits the result equals the number obtained by dividing their sum by 3, he showed them that the sum of the digits may be written thus: XLV, and that if the L, which represents 50, is removed, XV, or 15, the third of 45, remains.

In the “Geese to Market” problem—
B drove a goodly flock of geese,
And met with Farmer A;
Said Farmer A, “How much apiece
For this lot did you pay?”
Said B, “I paid for all I drive
Just six pounds and a crown,
And I am selling all but five
At the next market town.
If fifteen pence a head I charge
Beyond the price I paid,
I shall secure a sum as large
As he who sold all made.”
B bought 25 geese at 5s. each, and proposed to sell 20 of them at 6s. 3d.
