Boolean Logic
Boolean Logic
Whereas fuzzy logic is an approach to computing based on 'degrees of truth,' modern computing is based on Boolean logic, which is based on the usual 'true or false' (1 or 0) dichotomy.
Boolean logic provides the foundation for computers and other modern digital electronics. Digital logic circuits are one particular application of Boolean logic that uses voltage values to represent true and false, or 1 and 0.

Basic Logic Gates & Truth Tables
"OR False(0)" will keep as is
☹️ or ☹️ = ☹️
😃 or ☹️ = 😃
"OR True(1)" to force True(1)
☹️ or 😃 = 😃
😃 or 😃 = 😃
The nice kid, always obeys advice. It also tend to spread positive.(Does Dad ask me to eat?) or (Does Mum ask me to eat?) = (Do I eat?)
AND is as "Must...And Also..."
But not the general "...Together With..." or "...Also/Too..." meaning as in "ladies and gentlemen, may I have your attention...""AND False(0)" to force False(0)
☹️ and ☹️ = ☹️
😃 and ☹️ = ☹️
"AND True(1)" will keep as is
☹️ and 😃 = ☹️
😃 and 😃 = 😃
The teenager kid, ignores one parent, but obeys when both parents ask. It also tends to spread negative.(Does Dad ask me to eat?) and (Does Mum ask me to eat?) = (Do I eat?)

In Python, it's literally the same words as operations. Try out here
X = False
Y = False
Z = True
print((not(X) and Y) or Z)
