### Tell us what’s happening:

My code is doing what it is supposed to do in the preview window but when i run tests only the tests that is needed to raise an error passes while all other tests that should preview an answer fails

### Your code so far

```
def arithmetic_arranger(problems, show_answers=False):
#validating the limit of problems count
if len(problems) > 5:
return "Error: Too many problems."
#setting up initial rows strings

third_row = ""
forth_row = ""
for problem in problems:
#validating that the problem has only 3 parts
if len(problem.split(" ")) == 3:
pass
else:

number1 = problem.split(" ")[0]
operator = problem.split(" ")[1]
