प्रदृढं वा कर्तव्यं शुद्धया तेनापवत्र्य शेषं च । क्रियते मतिर्मतिमता तया पुनः कर्म कर्तव्यम् ।। १७ ।। दृढ़वासरे च गुणिते भाज्ये च तयोरदृढ़ता स्यात् । ताभ्यां दृढीकृताभ्यामेव तदा कर्म कर्तव्यम् ।। १८ ।। 2.८., “The dividend should always be of the same denomina tion as the interpolator which has been added or subtracted. So when the interpolator is the residue of the sign, etc., then the dividend should be multiplied by the number of signs, etc., (in a revolution) When the dividend as thus multiplied by the number of signs, etc., (in a revolution) is not prime to the divisor. then the process of the pulveriser should be performed with their actual (non-abraded) values, depending on the value of the residue (interpolator) (i.e., provided that the interpolator is completely divisible by the greatest common factor of the dividend as multi plied above and the divisor). In that case the multiplied divid end and the divisor as also the residue (interpolator) should be Imade prime to each other by dividing them by the (non-टero) remainder (of the mutual division of the first two). The intel ligent person should (in this case also) find out the mut and pro ceed further with it (in the mammer explained heretofore) (In case the interpolator is not exactly divisible by the great est common factor mentioned above, the following rule should be applied:) If the abraded number of days (viz. the abraded divisor) and the (abraded) dividend as multiplied (by the num ber of signs, etc., in a revolution) are found to be non-prime to each other, then the process of the pulveriser should be perform ed after having made them prime to each other
