1. Cobserve that two of the given numbers in your question are always of the same name, or kind; one of which must be the first nymer in stating, and the the third number : consequently, the first and third aume bers must always be of the same name, or kind: anıl the uther number, i hicho is of the saine kind with the answer.

The methodi vf proof is by inverting the question.
