The large white numbers against a black background may be easier to see for some people since the black background creates no glare. Big numbers on large keypads reduce the mistakes that some make when hitting the wrong number and the tiltable display shows the calculation in 1" high numbers. This calculator measures 11.5" x 8.5" x .4" and has 1" x .75" number pads. It uses an AG 13 battery (INCL).
