**Bhâskara II's Rules.** Bhâskara II (1150) says : "When the square of the unknown, etc., remain, then, multiplying the two sides (of the equation) by some suitable quantities, other suitable quantities should be added to them so that the side containing the unknown becomes capable of yielding a root (*pada-prada*). The equation should then be formed again with the root of this side and the root of the known side. Thus the value of the unknown is obtained from that equation."²
