    I'm kind of confused. Why does B -> C and A -> C lead us to A -> B? Isn't that mixing up necessary and sufficient?

    For eg:

    Bananas -> Fruits

    Apples -> Fruits

    ________________

    Apples -> Bananas?

    I actually like this analogy. I was always pretty decent at algebra. Let's see if it helps.

    Must be true indicates necessity while sufficient assumption indicates sufficiency.

    As an early elementary teacher, I loved the 2 + 3 and 2 + mystery analogy. It really helped me connect this way of thinking and learning to what I actually teach my kiddos

    For those that struggle with which group rules to follow, I use the order of the vowels finishing with a No.

    Group 1 | Group 2

    I for If | O for Only

    ———————————-

    Group 3 | Group 4

    U for /Unless | No for /No

    @emilylu when your platform charges based on time, so you make learning take as long as possible

    This section really ties all the questions together and why I got some wrong. Rule based ones are no bueno for me.

    They should put this section at the beginning of the module.

    @broenos #feedback 7s please do this. It would have prevented a ton of frustration and time wasted on my end. Will have to go back and review these things recommended after having gone through the entire module.

    @broenos most people would give up early if you put this at the beginning.
