'''Direct algebraic logic (D.A.L.)''' is a method for entering equations on scientific calculators which allows symbols and numbers to be entered as they are written. [[Sharp Corporation|SHARP]] introduced it in [[1992]]<ref>[http://sharp-world.com/contents/calculator/features/standard/dal D.A.L description] from Sharp</ref>. Today D.A.L. is used almost with every scientific calculator except those which use [[Reverse Polish Notation]].

Other known entry modes are '''Algebraic logic (A.L.)''' which was used in earlier calculators and [[BASIC]] notation which was used BASIC programmable [[Pocket computer|Pocket computers]]. Both can be seen as ancestors to D.A.L.
