”εκΏδα 212 - Multiply the square of the quotient by 300, calling it the triple square, and the quotient by 30, calling it the triple quotient, and the sum of these call the divisor. &. Seek how often the divisor may be had in the dividend, and place the result in the quotient.
”εκΏδα 19 - Place the least number under the greatest, so that units may stand under units, tens under tens, &c. and draw a line under them. 2. Begin at the right hand, and take each figure in the lower line from the figure above it, and set down the remainder.
