Zusammenfassung:	The utility model discloses an arithmetic exercise book with a ruler. The arithmetic exercise book consists of an arithmetic exercise book body and the ruler, and is characterized in that a left fixing clamp and a right fixing clamp are bonded to a binding line of the arithmetic exercise book body; and two ends of the ruler are fixed in the left fixing clamp and the right fixing clamp. The arithmetic exercise book with the ruler has a simple structure and is convenient to use; and a phenomenon that a student cannot do an arithmetic exercise when forgetting to carry the ruler is avoided.
