*To find whether any given year will be leap year. RULE.-Divide the given year by 4; if nothing remain, it is leap year; but if there be a remainder, that is the number of years after leap year.

EXAMPLE.

Was 1823 leap year?

4)1823

455-3 rem.

which shows it to have been the 3d after leap year.

The last year in every three centuries out of four, which would otherwise be leap year, is to be reduced to a common year.

To find whether the last year in any given century is leap year. RULE.-Divide the given century only, or the hundreds in the year, by 4; if nothing remain, it is leap year; but a remainder shows it is to be counted a common year.

EXAMPLE.

Will the year 1900 be leap year?

4)19(4

16

3 remainder; therefore a common year.

REDUCTION.

REDUCTION teaches to change the denomination of numbers without altering their value.

RULE.-When the reduction is from a higher denomination, to a lower, as pounds into shillings, tons into ounces, &c. multiply the highest denomination by as many of the next lower as make one of the highest, adding to the product the parts of the same name; multiply this sum by the next lower, adding to the product the parts of its own name, if any; and so on to the denomination required.

When the reduction is from a lower to a higher denomination, pence into pounds, minutes into days, &c. divide the given number by as many of that denomination as make one of the next higher, and so on, to the denomination required; and the last quotient with the several remainders, (if any) will be the answer required.

The proof is had by reversing the question.
