**Functions for mathematics are what elementary particles are for physics. **For this reason, the Scalar Calculator and its mathematical engine, provide the syntax for defining user functions, which is as close to natural as possible. Just enter f (x) = x^2 and you are ready to go. Stay tuned to learn a bit more details! π

## β Basic user defined functions

The syntax for defining user functions is as follows.
