Someone with good data management math skills, help please! (MDM 4U1)

Please help e answer this question. Please explain every step of the answer!
----> The final score of a soccer game is 6 to 3. How many different scores were possible at half-time ?
THANKS IN ADVANCE!!!! :)))))

Any score of the form a to b with a = 0, 1, 2, ..., or 6 and b = 0, 1, 2, or 3 is possible at halftime.

So, there are (6 + 1) * (3 + 1) = 28 possibilities
(Remember to count 0 for the above computation!)

I hope this helps!
