How can I step over simplification?

[ghost]

Hi,

I now found this lib and I think it really cool, so thanks for the project.
My doubt is just: how can I step on the simplification?

For exemple:
take a algebraic expression like: (a + 2a) /(a + 2a)*4 + 8 / 2
What I want to is:
1-use the simplify but with receive some notification that the (a +2a) was divided, like a event or even something likes. Is possible? How?
2-or, instead of 1 above, step each call to simplify soomething like this:
input = (a + 2a) /(a + 2a)*4 + 8 / 2
call 1 = 1 / 4 + 8 / 2
call 2 = 1 / 4 + 4
call 3 = 17 / 4
Each call happens only when I run the function, and so, I can register the steps, something like put some "explain" about it.

Some ideia on that?

Thanks!

The simplify function comes with a list of built-in rules (math.simplify.rules). You can pass your own list of rules as second argument, like simplify(expr, rules). If you want control over every step, you can write a loop yourself, pass only a single rule every time you execute simplify, and take the result as input for the second rule, etc.

I see. Thank you, I will search on the docs. Yesterday, I didn't tested the lib by myself, but just look over the examples. I will take a slow look at the docs and try by myself.
