Tell us what’s happening:

Why isn’t res defined?
I used a video to help me do this and the guy in the video used res without defining it and his code worked

Your code so far

import re

def arithmetic_arranger(problems, solve=False):
    if(len(problems)>5):
        return 'Error: Too many problems.'
    first=""
    second=""
    lines=""
    sumx=""
    string=""
    for problem in problems:
        if(re.search("[^\s0-9.+-]",problem)):
            if(re.search("[/]",problem) or re.search("[*]"), problem):
                return "Error: Operator must be '+' or '-'."    
            return 'Error: Numbers must only contain digits.'
        firstnumber=problem.split(" ")[0]
        operator=problem.split(" ")[1]
        secondnumber=problem.split(" ")[2]
        if(len(firstnumber)>=5 or len(secondnumber)>=5):
            return 'Error: Numbers cannot be more than four digits.'
        sum=""
        if(operator == "+"):
            sum=str(int(firstnumber) + int(secondnumber))
        elif(operator == "-"):
            sum=str(int(firstnumber) - int(secondnumber))

        length=max(len(firstnumber), len(secondnumber))+2
        top=str(firstnumber).rjust(length)
        bottom=operator+str(secondnumber).rjust(length-1)
        line=""
        red=str(sum).rjust(length)
        for s in range(length):
            line += "-"

        if problem != problems[-1]:
            first += top + " "
            second += bottom + " "
            lines += line + " "
            sumx += res + " "
        else:
            first+=top
            second+=bottom
            lines+=line
            sumx+= res
    if solve:
        string=first+"\n"+second+"\n"+lines+"\n"+sumx
    else:
        string=first+"\n"+second+"\n"+lines
    return string

You should not follow a video for these projects - that’s a violation of the academic honesty policy
