Short answer: A ⊊ B A ⊊ B means that A A is a subset of B B and A A is not equal to B B. Long answer: There is some confusion on mathematical textbooks when it comes to the symbols indicating one set is a subset of another. It's relatively clear what the symbol " ⊆ ⊆ " means. This symbol is more or less universally understood as the ...What Is the Symbol of Greater Than? In mathematics, the greater than relationship is denoted by a specific symbol: >. This symbol is like an arrow pointing to the smaller number, making it easy to remember that the larger number is greater than the smaller one. For example, we write 7 > 5 to show that 7 is greater than 5.7. As others have already mentioned it is usually called the "integral sign" or the "integral symbol" or just "integral" for short. Maybe more important is how the symbol shows up in context and how then to read it out loud. For example. ∫ f(x) dx ∫ f ( x) d x. can be read as "the integral of f f ". Or: "the indefinite integral of f f ".Symbol Symbol Name Meaning / definition Example { } set: a collection of elements: A = ...Related.
