• I thought the last video said odd times odd equals even?
• Is zero negative or positive?

• Good question! Zero is neither negative nor positive. Think of zero as neutral.

Only the numbers greater than zero are positive, and only the numbers less than zero are negative.

Have a good day!

• At of the video, David talks about that odd + odd = odd. But that doesn't make sense.. Because in "Intro to even and odd numbers", didn't he say that odd + odd = even?? & doesn't 3 x 3 = 6, 6 x 2 = 12, & 10 x 4 = 40-? I'm not sure if we really get this video.
• That is because in the other video was abourt addition. This is about multiplication.
• What does sum mean?
• The sum of two numbers is the combination of their values - that is, when you add them together.
The sum of `2` and `3` is `5`, just as `2 + 3 = 5`.
Same as product of two numbers -> multiplication.
The product of `2` and `3` is `6`, just as `2 * 3 = 6`.
Hope this helped!
