## Description

Dual Calculator: 2-in-1 puts two independent calculators on one screen, so you can keep one result while you calculate another.<br><br>Calculator A and Calculator B have separate inputs and separate results. Enter a calculation in Calculator A, leave the result visible, then use Calculator B for another calculation. An operation in one calculator does not affect the input or result in the other.<br><br>With a normal single calculator, starting a different calculation often means clearing the result you still need or trying to remember it.
