Description

A number of fractions has to be added or subtracted in a consecutive way. The number of problems and the number of fractions for each problem is selectable.

The fractions may be unlike quantities, in which case they have to be converted to like quantities first. The problem may be set to produce only chains of like quantities - or only unlike quantities.

The numerator and denominator of each fraction is taken from a preset number range.

The fractions' sign may be chosen to be positive (for addition) only, negative (for subtraction) only, or chosen randomly.

Improper fractions can be allowed, disallowed or enforced. In case they may occur, it can be chosen whether they will be output as improper fractions or mixed numbers.
