What does the E mean in 1e 9?
The e (or E ) means “times 10-to-the”, so 1e9 is “one times ten to the ninth power”, and 1e-9 means “one times ten to the negative ninth power”. In mathematical scientific notation, this is usually denoted by a superscript: 1 × 10-9 or -1 × 109.
The number e is one of the most important numbers in mathematics. e is an irrational number (it cannot be written as a simple fraction). e is the base of the Natural Logarithms (invented by John Napier). e is found in many interesting areas, so is worth learning about.

The intersection of a set A with a B is the set of elements that are in both set A and B. The intersection is denoted as A∩B. For example, if A is the set {♢,♡,♣,♠} and B is the set {△,♡,♠}, then A∩B={♡,♠}.
What is math Sigma?
