What is the big e in math?
The symbol ∑ indicates summation and is used as a shorthand notation for the sum of terms that follow a pattern.
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.
Why do we use the E key on a calculator?
Most scientific calculators devote a special key to Euler's number, because it is one of the most important irrational numbers in mathematics and enters into all kinds of scientific calculations. This is the "e" key. Press it, and Euler's number will appear in your display to the accuracy the display allows.
Why do calculators use lowercase?

How to enter scientific notation on a calculator?
It's the EE key. To enter a number in scientific notation, first input the argument, then press the EE key and enter the exponent. For example, to enter the mass of the earth, key in 5.97, then press the EE key and enter 24. The display will read 5.97E24 (or 5.97e24). Note that the number will appear with all its zeroes if they fit on the screen. For example, if you key in 1.2 EE 5, the display will show 120,000.
How does scientific notation work?
Scientific notation makes these numbers easier to handle by expressing the 0's as a power of ten. Using this notation, the mass of the Earth becomes 5.97 × 10 24 kg, and the mass of a hydrogen atom becomes 1.67 × 10 -27 kg. Instead of numbers with long strings of zeros that are difficult to count and even more difficult to display on ...
What is the symbol for X 10?
It would be confusing and it wouldn't fit on a small display. To avoid these problems, manufacturers created a symbol for "X 10." This symbol is either E or e , depending on the calculator. This letter is always followed by a number, which is the exponent to which 10 is raised.
What does the letter E mean in 4e14?
The letter E in 4e14 is used to mean exponent . One may also ask, what does E mean in scientific notation? In scientific notation, the letter E is used to mean "10 to the power of.". For example, 1.314E+1 means 1.314 * 101 which is 13.14 .
What is 9e + 10?
9e +10 => 9 is the first whole value number. => Where e stands for the number of zeroes next to 9. => where +10 means that there are positive (whole numbers) 10 zeroes next to 9. Therefore, 9e +10. => 90 000 000 000.
Why is there an e on my calculator?
The ‘e’ is there because the answer is too large to show on the limited digits of the calculator’s screen. The number after the ‘+’ sign represents the power of ten by which to multiply the first number on the screen.
What does the e followed by a number mean?
It means the answer is in scientific notation and most likely a very large number. The e followed by a number is 10 to the power of that number.
What is scientific notation on a calculator?
My calculator would use the capital E instead of the lower case e. I have not seen the lower case ”e” used. Scientific notation shows a number with a decimal, a fractional decimal portion times 10 raised to an exponent. In your case it is trying to say 20000000000, but it can’t write an exponent and put in a x10, that would be awkward and confusing. I am not 100% sure of the origins for the calculator’s use of E or e, but it sure looks like they lifted it from the FORTRAN programing language because FORTRAN and even BASIC used similar type output nomenclature and predates the calculator. You can think of it as meaning TIMES EXPONENT OF TEN. So just adjust your decimal point, to the right for positive numbers and left for negative numbers. This notation is what we lived with when we used real slide rules.
What is the decimal place of 5.5555853e+3?
A simple way of realizing this answer is to move the decimal place to the right by 15 numbers. If the answer were 5.5555853e+3, the answer would be 5555.5853 .
How to write a normal number?
If you want to write this number in normal number form, just move the invisible decimal point to the right, adding zeroes as necessary.
What does "exponent" mean in math?
It's short for exponent. It's a representation of the "scientific" notation for very large or small numbers, which writes these as a product of a power of 10 and a number between one and ten. Thus:
What is scientific notation?
See the other answers - there is nothing to add to them, except to say that scientific notation is a way of representing a huge range of values. For example, 7.3e300 would be 7.3 multiplied by 10^300. 5.7e-300 means 5.7 divided by 10^300. Scientific notation is closely related to floating point representation, used in programming.
