In mathematical logic, the operations “and” and “or” are marked with the symbols “Λ” and “V”. In the theory of multiplication, intersection and unification are marked with the symbols “∩” and “”. Summary of mathematical symbols for the intersection and union and and and Or When writing on paper or when the word processor supports superscript the exponent of the interpretation is displayed as superscript. However, it usually represents the exponentiation operation. The carriage symbol “^” may be confused with lambda “Λ”. Similarly, “X or Y” may be shown as “X || Y “instead of” X∨Y “. Only “AΛC” is true because each of the statements “A” and “C” is true.ĭepending on the programming language, “X and Y” may be represented as “X & Y” instead of “XΛY”. “X∨Y” is true if “X” or “Y” is true, which includes a situation where both “X” and “Y” are true.įrom the sample instructions “A∨B”, “A∨C” and “B∨C” are true. However, “X or Y” or “X∨Y” is false only if both “X” and “Y” are false. In mathematics, logic “X and Y” or “XΛY” is true only if both “X” and “Y” are true. Let “X” and “Y” represent all possible true or false statements. Let the statement A = “All men are mammals.” Let B = “All mammals are humans.” Let C = “Some birds may fly under certain conditions.” Both “A” and “C” are true statements, but “B” is false.
Our reader’s question also concerned ‘V’ and ‘upside down’ ‘V’, ‘Λ’ or Lambda. Math symbols can be confusing! Photo of JRS Regarding the original question, from the point of view of set theory, the word “relationship” refers to the symbol “∪” and the word “intersection” refers to the symbol “∩”.
The approach most similar to the question concerns set theory. We use Venn diagrams to show relationships and intersections. Venn diagrams for Unia image and intersection by Mike DeHana Set theory for connection and intersection The symbol for ‘Union of sets’ is ‘∪’, while the symbol for ‘intersection of sets’ is ‘∩’. ∧ is the big Greek Lambda.Ī small ^ or “peak” is available on most keyboards as “shift-6” symbolizes the power function. The “V” symbols in the reader’s question are ∨ and ∧, which means “Logical or” and “Logical and”. Mathematical symbols with questions about connection and intersection So let’s pay attention to our Us and V and their inverted companions in relationships and intersections and logical functions. What is the relationship between these symbols, which we sometimes call “U” and “V”? ” One is ∪ and upside down ∩, and the other is ∨ and ∧. Our reader’s question is: “There are two sets of symbols for” connection “and” intersection.
