......That
fondness for science, ... that affability and condescension which God shows
to the learned, that promptitude with which he protects and supports them
in the elucidation of obscurities and in the removal of difficulties, has
encouraged me to compose a short work on calculating by al-jabr and al-
muqabala , confining it to what is easiest and most useful in
arithmetic" [al-jabr means "restoring", referring to the
process of moving a subtracted quantity to the other side of an equation;
al-muqabala is "comparing" and refers to subtracting equal
quantities from both sides of an equation].......
