Hi fam and happy holidays to those celebrating!

I had a quick notation question if that's alright? So coming from a formal logic background and Powerscore tutoring, I was always told to notate an "and" statement like so:

..........B

A→ +

..........C

However, while I was foolproofing the Logic Games from PT 70 I came across J.Y's method/style:

A→B

↘ C

I do remember this notation from my 7 sage days years ago and more recently from some lessons upon my return, so I tried it. No surprise, it made the game infinitely easier (Game 2 for reference).

My question is this: Are there situations where one style is better than the other and if so what are they?

Thanks for your time!

    Really comes down to what you find easiest. I also took modal logic in university. I just use ampersands.

    A --> B & C

    A

    Therefore

    B&C (1,2)

    B (3)

    C (3)

    They're essentially the same thing, but I personally prefer 7sage's method because it's more visual to me and makes chaining a lot easier. I think it really comes down to what you think works best for you in terms of efficiency. Happy holidays!
