The 2nd to last row on the number pad on the calculator displays the units below it.

When I press number “1” it shows “0”

When I press “2” it shows “ . ”

when I press “3” it shows EXP

When I press “-” it press “EXE” (enter)

whatever I press on the 2nd to the last row displays the units that are in the last row.

Please help me thanks.
