I’m wondering how the computer is getting 5 + 4 to equal 10???
Hi, @mycatisloud! Welcome to the forums 
Your sumNumbers function is taking only one parameter, number. Then it will return the result of adding number to itself once. I’m assuming it’s taking the 5 as the argument and therefore it prints 10 (since it’s just adding 5 + 5)
Hope this helped
