you should place them in the order they were listed when you created the function.
E.g. you cannot write "printTimesTables(end: 20, number: 5)" swift will not allow it

Sum / Count until a certain point
Example 1;
let number1 = 10
let number2 = 14
var multiples = [Int]()
for i in 1...100_000 {

}
print(multiples)
// print: [70, 140, 210, 280, 350, 420, 490, 560, 630, 700]
Example 2;
let scores = [1, 8, 4, 3, 0, 5, 2]
var count = 0
for score in scores {
if score == 0 {
break
}
count += 1
}
print("You had \(count) scores before you got 0.")
// print: You had 4 scores before you got 0.
