The Formula Explained
Scientific Notation = Number × 10Exponent
Glossary of Terms
- Scientific Notation: A way of expressing numbers that are too large or too small to be conveniently written in decimal form.
- Exponent: The power to which a number is raised in scientific notation.
How It Works: A Step-by-Step Example
Consider the number 12345. In scientific notation, it's written as 1.2345 × 104. The exponent 4 shows the number of places the decimal point has moved.
Frequently Asked Questions (FAQ)
What is scientific notation?
Scientific notation is a method of writing numbers as the product of a coefficient and a power of 10.
Why use scientific notation?
It's used to simplify calculations with very large or very small numbers, often found in scientific and engineering contexts.
How do you convert a number to scientific notation?
Move the decimal point in the number until only one non-zero digit remains on the left. Count the number of places the decimal has moved; this is the exponent.
Can all numbers be converted to scientific notation?
Yes, any real number can be expressed in scientific notation.
Is scientific notation used in everyday life?
While it's primarily used in scientific fields, it can also be useful in financial calculations and data analysis.
