### Tell us what’s happening:

Code seems like it follows all the rules, but doesn’t pass about half the tests. I got it so all the error messages are good, as those just needed periods, but despite the output looking perfect otherwise it won’t count it as passing the tests.

### Your code so far

```
def arithmetic_arranger(problems, show_answers=True):
if len(problems) > 5:
return('Error: Too many problems.')
#Lists of the first and second numbers in math problems
first_number = []
plus_or_minus = []
second_number = []
max_length = []
for problem in problems:
#Splitting the first number, +/-, and second number into different lists
problem_parts = problem.split()
first_number.append(problem_parts[0])
plus_or_minus.append(problem_parts[1])
second_number.append(problem_parts[2])
if problem_parts[1] == '*' or problem_parts[1] == '/':
return("Error: Operator must be '+' or '-'.")
if len(problem_parts[0]) > 4 or len(problem_parts[2]) > 4:
return('Error: Numbers cannot be more than four digits.')
if not (problem_parts[0].isdigit() and problem_parts[2].isdigit()):
return('Error: Numbers must only contain digits.')
#Getting the length of the largest number in the problem so the problem has space
problem_length = max(len(problem_parts[0]), len(problem_parts[2])) + 2
max_length.append(problem_length)
#Making the lines of text for the math problem
first_line = ''
second_line = ''
dashes_line = ''
answer_line = ''
for i in range(len(problems)):
first_line += first_number[i].rjust(max_length[i]) + ' '
second_line += plus_or_minus[i] + second_number[i].rjust(max_length[i] -1) + ' '
dashes_line += '-' * max_length[i] + ' '
if show_answers:
answer = str(eval(problems[i]))
answer_line += answer.rjust(max_length[i]) + ' '
#Put lines together
rearranged_problem = first_line.rstrip() + '\n' + second_line.rstrip() + '\n' + dashes_line.rstrip()
if show_answers:
rearranged_problem += '\n' + answer_line.rstrip()
print(rearranged_problem)
return problems
print(f'\n{arithmetic_arranger(["32 + 698", "3801 - 2", "45 + 43", "123 + 49"])}')
```
