CALC 1 Register Arithmetic Calculations

CALC 1 uses the following keys for register arithmetic and repetitive adding, subtracting, multiplying and dividing.

 

Key Label Hint X Formula
STO ra÷x Divides the register arithmetic variable by x. raValue = raValue / rgX()
STO ra*x Multiplies the register arithmetic variable by x. raValue = raValue * rgX()
STO ra-x Subtracts x from the register arithmetic variable. raValue = raValue - rgX()
STO ra+x Adds x from the register arithmetic variable. raValue = raValue + rgX()
RCL x÷ra Divides x by the register arithmetic variable. rgX() / raValue
RCL x*ra Multiplies x by the register arithmetic variable. rgX() * raValue
RCL x-ra Subtracts the register arithmetic variable from x. rgX() - raValue
RCL x+ra Adds the register arithmetic variable from x. rgX() + raValue
STO ra Stores the register arithmetic variable. raValue = rgX()
RCL ra Stores the register arithmetic variable. raValue
