Addition, subtraction, multiplication and division are the four basic operations of elementary arithmetic.

module.exports.addition = function (a, b) {
  return a + b
};

module.exports.subtraction = function (a, b) {
  return a - b
};

module.exports.multiplication = function (a, b) {
  return a * b
};

module.exports.division = function (a, b) {
  return a / b
};
