For example:
Extended data
There are three Boolean operations: OR, AND and NOT.
Representation method
∨ "means" or ".
∧ "means" harmony ".
"┐" means "no".
"=" means "equivalence".
1 and 0 mean "true" and "false"
There is another expression, "+"means "or" and "means" and ".
Boolean operation is a logical deduction method of digital symbolization, including union, intersection and subtraction. This logical operation method is used in graphic processing operation, which makes simple basic graphic combination produce new shapes. It develops from two-dimensional Boolean operation to three-dimensional Boolean operation.
Because of Boolean's special contribution to symbolic logic operation, many computer languages call logic operation Boolean operation and its result Boolean value.
