Modern computer algebra systems, as well as many scientific and graphing calculators, allow for "'''pretty-printing'''", that is, entry of equations such that [[Fraction (mathematics)|fractions]], [[Nth root#Definition and notation|surds]] and [[integral]]s, etc. are displayed in the way they would normally be written. Such calculators are generally similar in appearance to those using infix notation, but feature a full dot-matrix display and templates for entering expressions, which are navigated using arrow keys on the calculator. The templates contain spaces for values or expressions to be entered, and empty values would typically result in a syntax error, making it more cumbersome to navigate than standard infix notation; standard infix notation is often an option on such calculators as well.
