Personalty I do because unlike conventional social media the people here are a nicer and more intelligent.
I hopefully think that perhaps I have experienced things in my colorful life, or at least researched or read about so many things, that I can help others.
32/4 = 8
John = 8 x 3 = 24
Mark = 8 x 1 = 8
Check it: 24 + 8 = 32
J + M = 32
J = 3M
4M = 32
M = 8
Mark has 8 Marbles, John has 24
Of course you didn't NEED algebra for this, I was just showing off :)
