Receiving "Math Processing Error" in description Loops / List Comprehension

[edutools-service]

receiving the following:
my_inefficient_list by adding [Math Processing Error]
to each of them. For example, the first element of my_inefficient_list is [Math Processing Error]
, so the first element of my_efficient_list should be [Math Processing Error]
, and so on.

Assuming that the [Math Processing Error] is not intentional.
