Example
Use the M register to add 17, 14.25, and 16.95. Then subtract 4.65 and recall the result.
Using Numbered Registers
The \w and v keys access the 20 user registers, designated 0-19. The
\w key is used to copy the displayed number to a designated register. The v key
is used to copy a number from a register to the display.
To store or recall a number in two steps:

•Press
\w followed by a number key, : to d, or 7 and : to d, to store a
number in the display into a numbered data storage register. Press
\w7 followed by
: through d to access registers 10-19.
•Press
v followed by a number key, : to d, or 7 and : to d, to recall a
number from a storage register. Press
v7 followed by : through d to access registers
10-19.
