Direct Algebraic Logic
For most scientific calculators, keying in an equation is a complicated process. But with D.A.L., a feature unique to Sharp scientific calculators, symbols and numbers can be keyed in as written.
Two-line display allows the users to check both the equation and answer at the same time. And since the equation remains displayed, it is easy to edit or make substitutions if necessary.
Simply replace values in an algebraic formula with the convenient Value.
