In the following four problems, note how the
arithmetic solutions use logic and involve a probing of the conditions of
the problem—procedures which often easily transfer to the more abstract
process of algebraic solutions, where problems ultimately are reduced to
One raja says to another, “If you give me one
camel, then we will have an equal number of camels” The other replied, “No,
if you give me one camel, then I will have double the number you have.” How
