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 all the numerical values in the separate 

variable M, press 

 

 

 

 (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, 

 

 

 

. This clears variable A.

• To clear the values of all variables, press 

 

 

 (Mcl)

• Example:

1234
