You can do basic calculations like:
2+3, 2-3, 2*3, 3/2, 2^3, 5*(2-6).
The calculator knows the constants
You can use the functions
sin, cos, exp, log, log10.
Conveniently it knows factorials, e.g.
You can set the value of a variable and use it later. You do this by separating multiple expressions by semicolons.
Try the following:
x=5; y=6; x*y
x=3; y=x^2+1; z=(x+1)/y; z
The features are quite extensive. See Mathjs documentation.
