Variable M
You can use the variable M to compute
accumulated totals which can be put into the
variable M directly, or they can also be added to or
subtracted from the number stored in variable M.
To clear the numerical values the
separate variable M, p r e s s I s h W I |It^ P m ] (M+)

Variables
There are 9 variables: A to F, M, X and Y. These
are used for storing data, constants, calculation
results and other numerical values.
To clear a single variable, store zero into it. For
example, fol H |^ P+l
This clears variable A.
To clear the values of all variables, press [»i]
