## Long description

The Casio WM-320MT pocket calculator features an extra large 12-digit single-line display that makes numerical data easy to read.

Plastic keys are engineered for easy and reliable operation. Dedicated functions for cost/sell/margin and tax calculations speed up common retail and accounting tasks. Function command symbols on the display indicate the current arithmetic operation.
