Well, isn't that a happy little puzzle! To find two numbers that multiply to 20 and add up to 4, we can think about our options. The numbers are 2 and 10 because when you multiply them, you get 20, and when you add them, you get 12. But if you switch things around and use 4 and 5, they multiply to 20 and add up to 9. It's all about playing with numbers and finding the right combination that brings a smile to your canvas!
