| Jan 3, 2016 at 22:18 | comment | added | user8572 | +1. Thank you. Not comprehending anything else, I comprehended the quote he Peano Formulaire vol.2, page 26, because '⊂' = 'conséquence'. Will you please summarise the first blockquote? I am confused because is it implying that '⊂' for 'consequence' somehow connects to the mathematical meaning of '⊂' (ie: 'contains')? If so, how? | |
