## Standard Notation

This is a simple way to write all numbers with commas and decimals, you can even write it without commas. For example 23456, 1800, the calculation will as simple as 123 + 10 = 133, 113 – 11 = 102, 3 × 4 = 12, and 10 / 2 = 5.

## Scientific Notation

Scientific notation is the way to represent or write a very large or small number in an authentic form. This expression is mostly used by mathematical scientists and engineers in their researches and theories.

### Engineering Notation

It is the same as scientific notation but is limited to the multiples of 3 like 0, 3, 6, 9, – 3, -6, -9 and so on. Its prefix will write as 10^{3} in the Kilo, Mega will be 10^{6} and Giga prefix will be 10^{9}, etc while keeping in mind that its decimal part will move from scientific notation to engineering notation such as 1.34×10^{8} to 1.34×10^{6}.

### E Notation

This notation form is also the same as the scientific notation, but only the “×10” part will replace with **E** such as 3×10^{2 }= 3E2 and 2×10^{6 }= 2E6 and so on.

## Mathematical Operations

This calculator basically performs 4 mathematics operations for scientific notation numbers that are explained below in detail.

### Addition

The addition in scientific notation is simple like normal maths addition such as n_{1} + n_{2} = a×10^{n} + b×10^{m} = (6.43×10^{3}) + (4.36×10^{4}) = 5.00×10^{4}, but you this manual calculation, you can do more complex big calculation within second with the above online calculator.

### Subtraction

The subtraction is also like addition such as n_{1} – n_{2} = a×10^{n} – b×10^{m} = (6.43×10^{3}) – (4.36×10^{4}) = -3.717×10^{4}, you can use this calcultor for fast subtraction.

### Multiplication

The multiplication is little different, first, you need to multiply the decimal number and add the power values with each other such as n_{1} × n_{2} = (a×b)10^{n + b} = (6.43)(4.36)×10^{3+4}= 2.80×10^{4}.

### Division

The division operation is like multiplication but the power values will be subtract from each other such as n_{1} / n_{2} = (a/b)10^{n + b} = (6.43)/(4.36)×10^{3-4}= 1.47×10^{-1}.

# Frequently Ask Questions

## What is E in the Calculator?

Calculator simply displays the E instead of “×10” fox example the number of 25 trillion will display as 2.5E13 and so on.

## What is the Standard Notation for 7.5e5?

It is very simple, as the e5 stands for ×10^{5} so the standard form of 7.5e5 is equal to 0.000045.

## Why is Scientific Notation Important?

It has many applications and very important in every field but mostly uses by scientists and mathematization to write a very large number more conveniently.

## How is Scientific Notation Used in Chemistry?

As we discuss the uses of the scientific number already, but in chemistry, we can simply say that it shows a large number of chemical formulas authentically.

## How Do You Write 0.00001 in Scientific Notation?

As it is a negative number because it is smaller than 1, so it will be scientifically written as 1.0×10^{5}.
