Yes that's exactly the case (sorry for any confusion folks).

The code simply generates problems for the student/enthusiast
to solve. The books I've read use the symbols we all know.
But some older books complained that: 5y is ambiguous &
would be better expressed as: 5 * y, where * is the actual
multiplication symbol in the book & y is the variable.

In the code posted, I'm using 7bit ASCII for all operators:

* multiplication 2 * 2 = 4

/ division       4 / 2 = 2

+ addition       2 + 2 = 4

- subtraction    2 - 2 = 0

^ power          2 ^ 2 = 4

_nth subscript   a_1 (1st element in array a[1])

%                modulus

|                or

(), [], {}       order does not matter, evaluate inner
                 to outer before outside expressions
                 {2 / [(x + y + z) - 2]}

r!               factorial 4! = 4 * 3 * 2 * 1 = 24

=                equals

!=               not equal

~                approximately equal

f(a, b) = a + 10 function definition

how to handle matrices?

[x y
 0 1]

[x y]
