You usually see the capital E on a calculator, where it means to raise the number that comes after it to a power of 10.

For example, 1E6 would stand for 1 x 106, or 1 million..

## What does N mean in math?

## Is there a symbol for with?

A c with line over it medical abbreviation is a common abbreviation used by doctors, nurses, and other medical professionals to take the place of the word “with.” The symbol c comes from the Latin word for “with,” which is cum.

## What does R mean in math?

## What is the U symbol in math?

In set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. It is one of the fundamental operations through which sets can be combined and related to each other. For explanation of the symbols used in this article, refer to the table of mathematical symbols.

## What does ≡ mean in math?

(mathematics) “is equivalent to” (mathematics) “is identically equal to”. “is defined as” or “is set to”. The functions f and g satisfy f≡g if and only if their respective domain of definition coincide, and if f(x)=g(x) for all x in this domain.

## What this symbol means?

This symbol < means less than, for example 2 < 4 means that 2 is less than 4. This symbol > means greater than, for example 4 > 2. ≤ ≥ These symbols mean ‘less than or equal to’ and ‘greater than or equal to’ and are commonly used in algebra. In computer applications <= and >= are used.
