Tell us what’s happening:
my code cant seem to pass on tests example, but it passes on the preview menu,
Where did i get wrong or which line is not right?

please help me.

Your code so far
```
def arithmetic_arranger(problems, show_answers = True):
if len(problems) > 5 :
return "Error: Too many problems."
# Initialize variables
first_line = ""
second_line = ""
dashes = ""
answers = ""
def operator_func( num1 , operator,num2):
if operator not in ['-','+']:
return 'Error: Operator must only contain digits.'
if operator == '+':
return int(num1) + int(num2)
elif operator == '-':
return int(num1) - int(num2)
# Loop through problems
for problem in problems:
num1, operator, num2 = problem.split()
if not num1.isdigit() or not num2.isdigit():
return "Error: Numbers must only contain digits"
if len(num1) >4 or len(num2)>4:
return'Error: Number cannot be more than four digits'
# Format problem strings
max_len = max(len(num1), len(num2)) + 2
first_line += num1.rjust(max_len)
second_line += operator + " " + num2.rjust(max_len - 2)
dashes += "-" * max_len
# Return arranged problems
if show_answers:
return first_line + "\n" + second_line + "\n" + dashes + "\n" + answers
else:
return first_line + "\n" + second_line + "\n" + dashes
print(arithmetic_arranger(["3801 - 2", "123 + 49"]))
print(arithmetic_arranger(["1 + 2","1 - 9380"]))
```

Build an Arithmetic Formatter Project - Build an Arithmetic Formatter Project

it doesn’t pass on the previous, you have two function calls

```
print(arithmetic_arranger(["3801 - 2", "123 + 49"]))
print(arithmetic_arranger(["1 + 2","1 - 9380"]))
```

and the preview shows only one problem for each

```
123
+ 49
-----
1
- 9380
------
```

you are missing the first problem for both calls

how do i call the first problem, anothewr thinf thers no answer showing

i have added the zswer line : answers += str(problem).rjust(max_len)
but it show 988 +40

I don’t understand your question

which part of your code is dedicated to calculating the sum?

f show_answers:
answer = operator_func(num1, operator, num2)
answers += str(answers).rjust(max_len) + " "

can you post your full code again? I don’t see a call to `operator_func`

in the code you posted earlier

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (`</>`

) to add backticks around text.

Indentation is really important in python, please use the backticks to format your code so that it is readable.

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

you do not have a `return`

anymore, it’s quite difficult to review incomplete code

```
def arithmetic_arranger(problems, show_answers = True):
if len(problems) > 5 :
return "Error: Too many problems."
# Initialize variables
first_line = ""
second_line = ""
dashes = ""
answers = ""
def operator_func( num1 , operator,num2):
if operator not in ['-','+']:
return 'Error: Operator must only contain digits.'
if operator == '+':
return int(num1) + int(num2)
elif operator == '-':
return int(num1) - int(num2)
# Loop through problems
for problem in problems:
num1, operator, num2 = problem.split()
if not num1.isdigit() or not num2.isdigit():
return "Error: Numbers must only contain digits"
if len(num1) >4 or len(num2)>4:
return'Error: Number cannot be more than four digits'
# Format problem strings
max_len = max(len(num1), len(num2)) + 2
first_line += num1.rjust(max_len) + " "
second_line += operator + " " + num2.rjust(max_len - 2) + " "
dashes += "-" * max_len + " "
answers += str(problem).rjust(max_len)
# Return arranged problems
if show_answers:
answer = operator_func(num1, operator, num2)
answers += str(answers).rjust(max_len) + " "
return answers
print(arithmetic_arranger(["3801 - 2", "123 + 49"]))
```

what questions do you have for this code?

Here is the function call and output from your code:

```
print(arithmetic_arranger(["3801 - 2", "123 + 49"]))
123 + 49123 + 49
```

It should look like this:

```
3801 123
- 2 + 49
------ -----
```
