The following list shows all operators recognized by iMath, from lowest precedence to highest precedence. Operator precedence defines the order in which operators are evaluated when no brackets are set. For example, 3 * 4 + 5 will evaluate to 17, not to 23, because + has lower precedence than *.

  • ## Matrix definition
