Euclid  
You can define variables for use at a later time. To list all currently defined variables by using the command "variables". Examples: Enter command: c = sqrt(2) Variable: c = ( 1) * sqrt(2) Enter command: d = c * c Variable: d = 2 result variable Whenever you enter an expression to be evaluated, the result is stored in the variable "result". You can use this as just any other variable in the next expression to evaluate. For example: Enter command: 5 + 6 Enter command: 1 / result Result = (1 / 11)
