The Arithmetic Reasoning section of the ASVAB test focuses on word problems and delivers mathematical questions and equations in a format that must be synthesized. The Python programming language has basic commands which implement integer arithmetic. Modular arithmetic is a special type of arithmetic that involves only integers. In modular arithmetic, numbers "wrap around" upon reaching a given fixed quantity (this given quantity is known as the modulus) to leave a remainder. 2 (Prime number).
