Interestingly, order of evaluation is just a convention.
This order of evaluation is the reverse of the APL one.

Is there any way to unpublish a kata? All the solutions will be invalidated.

My solution was approved and was then removed because of this issue, should I repost it, or will it come back by itself into the solutions?

Resolving here, same issue above. I'll take a look in a minute

Python: The following test (and many random tests with `^`) is incorrect:

`test.assert_equals(no_order(' 3-15 ^ 8-4 '), -429981700)`

The result should be `429981692` because: 3 - 15 = -12, (-12)^8 = 429981696, 429981696 - 4 = 429981692.

In Python, the expression `-12 ** 8` is evaluated as `-(12 ** 8)` which is not correct for this kata.

I think exponentiation implementation in tests is wrong.

``````Log
3-15 ^ 8-4

429981692 should equal -429981700

``````

but

``````3-15 = -12
(-12) ^ 8 = 429981700 and  not -(12**8)
``````

Really interesting , in my opinion much harder than the other performance oriented kata , I'm at 2.5 millions in 12 sec for now :D
