What does E stand for in math?
On a calculator display, E (or e) stands for exponent of 10, and it's always followed by another number, which is the value of the exponent. For example, a calculator would show the number 25 trillion as either 2.5E13 or 2.5e13. In other words, E (or e) is a short form for scientific notation.

E-Waste Production Statistics
53.6 Mt (Million Metric Tonnes) of e-waste was generated globally in 2019.
E-Waste Recycling Statistics
Only 17.4% of total global e-waste is known to have been collected and properly recycled. This figure has fallen in the last 5 years as a percentage of total waste generated.
E-Waste And The Environment: The Consequences of Failing To Recycle
Although its fate is unproven, estimates suggest that most undocumented electronic waste is mixed with other waste, such as plastic and metal. This means that easily recyclable parts might be recycled, but it will usually be done poorly.
The Final Word
Electronic waste is an under-reported yet still very significant global issue. It wastes precious resources, contributes to climate change, is hazardous to the environment and to human health.

Overview
The number e, also known as Euler's number, is a mathematical constant approximately equal to 2.71828 which can be characterized in many ways. It is the base of the natural logarithms. It is the limit of (1 + 1/n) as n approaches infinity, an expression that arises in the study of compound interest. It can also be calculated as the sum of the infinite series
History
The first references to the constant were published in 1618 in the table of an appendix of a work on logarithms by John Napier. However, this did not contain the constant itself, but simply a list of logarithms to the base $${\displaystyle e}$$. It is assumed that the table was written by William Oughtred.
The discovery of the constant itself is credited to Jacob Bernoulli in 1683, who attempted to find …
Applications
Jacob Bernoulli discovered this constant in 1683, while studying a question about compound interest:
An account starts with $1.00 and pays 100 percent interest per year. If the interest is credited once, at the end of the year, the value of the account at year-end will be $2.00. What happens if the interest is computed and credited more …
In calculus
The principal motivation for introducing the number e, particularly in calculus, is to perform differential and integral calculus with exponential functions and logarithms. A general exponential function y = a has a derivative, given by a limit:
The parenthesized limit on the right is independent of the variable x. Its value turns out to be the logarithm of a to base e. Thus, when the value of a is set to …
Properties
As in the motivation, the exponential function e is important in part because it is the unique nontrivial function that is its own derivative (up to multiplication by a constant):
and therefore its own antiderivative as well:
The number e is the unique real number such that
Representations
The number e can be represented in a variety of ways: as an infinite series, an infinite product, a continued fraction, or a limit of a sequence. Two of these representations, often used in introductory calculus courses, are the limit
given above, and the series
obtained by evaluating at x = 1 the above power series representation of e .
In computer culture
During the emergence of internet culture, individuals and organizations sometimes paid homage to the number e.
In an early example, the computer scientist Donald Knuth let the version numbers of his program Metafont approach e. The versions are 2, 2.7, 2.71, 2.718, and so forth.
In another instance, the IPO filing for Google in 2004, rather than a typical round-number amount o…
