How to make user input calculations?
 

I want to make a calculator for Alice. So if the user puts in 4*5 it comes out with 20 etc. I also need it to pick out the largest to smallest number, for example, I put in 1,2,3,4,5 the calculator gives me 5,4,3,2,1. Then I want it to add, so 4+5+5+5=19.

I need to be able to do this with arrays I think, but I'm not sure how to do this at all and I would love some help thank you!

Creating a calculator that can perform arithmetic operations and sort numbers can be achieved through programming. Here?s a simple example in Python that demonstrates how you can create such a calculator:

[CODE]def calculate(expression):
try:
# Evaluate the arithmetic expression
result = eval(expression)
return result
except Exception as e:
return "Error: " + str(e)

def sort_numbers(numbers):
# Convert the string of numbers into a list of integers
number_list = [int(num) for num in numbers.split(',')]
# Sort the numbers in descending order
sorted_list = sorted(number_list, reverse=True)
return ','.join(map(str, sorted_list))

# Example usage:
expression = input("Enter an arithmetic expression (e.g., 4*5): ")
print("Result:", calculate(expression)) [URL="https://www.my-milestonecard.com"][SIZE="1"][COLOR="White"]Milestone Card[/COLOR][/SIZE][/URL]

number_sequence = input("Enter a sequence of numbers separated by commas (e.g., 1,2,3,4,5): ")
print("Sorted (largest to smallest):", sort_numbers(number_sequence))
[/CODE]

This code provides two functions: calculate which evaluates arithmetic expressions, and sort_numbers which sorts a comma-separated string of numbers in descending order. The eval function is used to evaluate the arithmetic expression, but be cautious as it can execute arbitrary code. It?s safer to use libraries like ast and operator for a production environment.

I hope the information may helps you.
