Scientific Notation Calculator

Welcome to our scientific notation calculator!

Actually, our app is a scientific notation conversion calculator because it can do both, convert and calculate.

How the Calculator Works

When you come to this page, then the calculator is shown in expanded form so that you can carry out the mathematical operation you want.

Fill in the first value, then click the corresponding operation symbol:

Our scientific notation calculations include adding, subtracting, dividing as well as multiplying scientific notation.

Next fill in the second value.

There is no result button, because the outcome is computed automatically once all required input forms have been filled.

Note that you can optionally switch to e notation as well as to decimal notation – the numbers and the result always follow.

It essentially means that our app is also a decimal to scientific notation converter, and vice versa.

In this case you may want to press collapse first.

Needless to say that you can expand our online tool (again) after that.

BTW: If you are looking for a scientific calculator, we recommend the one you find on google.com.

Scientific Notation Terms

For m × 10n we employ the following terms:
  • Coefficient: m, also called significand and mantissa
  • Base: 10
  • Index: n, also called exponent
  • Normalized notation: 1 ≤ |m| < 10
  • Significant figure: A digit in the coefficient that adds to its precision.

Scientific Notation Calculator Multiplication

Scientific notation multiplication uses the multiplying exponents rule known from exponentiation.

a × 10n × b × 10m = (a × b) × 10n+m

Example:

4 × 102 × 2 × 103 = 8 × 105

Scientific Notation Calculator Division

Scientific notation division uses the dividing exponents rule also known from exponentiation.

a × 10n / b × 10m = a/b × 10n-m

Example:

4 × 104 / 2 × 102 = 2 × 102

Scientific Notation Calculator Addition

Scientific notation additions requires the same exponents for both summands; thus that the significands can be simply added:

a × 10n + b × 10n = (a + b) × 10n

Example:

1.5 × 103 + 3.25 × 103 = 4.75 × 103

Scientific Notation Calculator Subtraction

Scientific notation subtraction requires the same exponents for both terms; thus that the significands can be simply subtracted:

a × 10n – b × 10n = (a – b) × 10n

Example:

4 × 106 – 2 × 106 = 2 × 106

FAQs

Click on the question which is of interest to you to see the collapsible content answer.

What are the scientific notation’s parts?

The scientific notation format consists of the coefficient (followed by the multiplication symbol). Next is the base and index.

What is the difference between a calculator and a scientific calculator?

The term “scientific calculator” often means a calculator like the one of your Windows switched from standard mode to scientific mode to calculate logarithms, trigonometric functions, square roots etc.

How to multiply and divide scientific notation?

Employ the laws of exponents.

Can scientific notation be a source of error in measurement?

Yes, if not enough significant figures are used.

What is the meaning of e on a calculator?

E on a calculator stands for exponent or exponent button.

What is the difference between scientific and engineering notation?

Engineering notation is a special form of scientific notation in which the integer exponent must be divisible by three zeros. E.g. 3 for thousand, 6 for million, 9 for billion etc.


We also have students practice: scientific notation practice. Or would you rather take our quiz with questions in the context of this site?

Summary

As you have learned, our calculator tool is a kind of Swiss Military knife built around scientific notation:

From scientific e notation to decimal notation calculator – it does it all.

The basic difference to an exponent calculator is that the base is always 10.
