just type the expression you want to calculate and press enter, for example,
> 1 + 1
will come up with the result
1 + 1 --> 2 (R1)
2
the last line is the result of the express.
Every expression evaluated is assigned to a variable starting with R1. so this variable can
be used in next expression. for example,
>1+1
1 + 1 --> 2 (R2)
2
>R1 + 5
R1 + 5 --> 7 (R2)
7
Functions can be used in the expression.
>sqrt(90)
sqrt(90) --> 9.486832980505138 (R1)
9.486832980505138
