For your example, it could give:

ListOperations := module () export `+`; option package;

`+` := proc (a::list, b::list) option overload; [op(a), op(b)] end proc:

end module:

with(ListOperations);
[+]
[a, b, c]+[d, e, f];
[a, b, c, d, e, f]

## Seq...

Hi, you could try:

[seq(M[j][1] = 0, j = 1 .. 5)];

solve(%,{x[1],x[2],y[1],y[2],y[3],y[4],y[5]})

## Operator inert from...

Hi, Try:

`%>`(2*x-5, 3*x-6)

Be aware that "solve" do not handle quantum operators and gives an incorrect result:

This result ((5)) is incorrect because solve has considered all variables as commutative ones. Up-to now, there is no other way than to solve the equation manually. It is useful to introduce the commutator of x and y, that is:

You could also try "Fundiff" from the Physics Package.

## Extra space...

There is a space between "Matrix" and "'(". Remove it, and it should work.

## subs then coeff...

Try (works with M2016):

subs(1/g(z)^2 = A, yourexpression): coeff(%, A)

## Quantum operators...

You could try quantum operators from the Physics Package. A quantum operator is a non-commutative linear operator that is a very good symbolic representation of a matrix. At the end, you still have to solve your equation manually, but the non-commutative feature of matrices will be respected.

## Shift+F5...

"Place the cursor in each math expression and press Shift+F5. This will make the expressions non-executable. See ?worksheet,documenting,2DMathDetails."

## Inert form...

You could try the inert form:

%sin(x+y+z-Phi)

And, if necessary, to enhance the display use:
