Arithmetical Problems, Riddles, Oracles
Not only Nos. 116–146, but the rest of the arithmetical problems in this book may be put down to Metrodorus, if we may judge by the style. This Metrodorus was probably a grammarian of the time of Constantine the Great.
The problems, which are all of the same nature, can be easily solved by algebra. The Scholiast gives somewhat cumbrous arithmetical solutions.
