3. Calculations Using MATH Menu
The Advanced keyboard has considerably more MATH menu items to choose from
than that of the Basic keyboard:
A CALC Contains sub-menu tools for advanced calculations. To access
each sub-menu item, make sure that this A CALC menu item is
selected. Pressing the ' cursor key will extend the cursor to
the sub-menu items. Items can then be highlighted by scrolling
with {, }, ; or ', and selected by pressing
E, or simply use the short cut key stroke (i.e., select 01 by
