What is scientific notation?

Scientific notation is a way of expressing very large or very small numbers in the form of a × 10ⁿ, where a is a coefficient and n is an exponent.

Why use scientific notation?

It makes working with extremely large or small numbers easier and more readable in scientific and engineering fields.

How do I convert a number to scientific notation?

Move the decimal point until only one nonzero digit remains on the left, then count the moves as the exponent of 10.

Can I convert scientific notation back to decimal?

Yes! Multiply the coefficient by 10 raised to the exponent to get the decimal form.

Is scientific notation used in real life?

Yes, it's commonly used in physics, chemistry, astronomy, and engineering to simplify calculations.

Scientific Notation Rules

Format	Example	Decimal
a × 10ⁿ	1.23 × 10⁴	12,300
1 ≤ \|a\| < 10	5.67 × 10⁻³	0.00567
n is integer	7.89 × 10⁰	7.89

• The coefficient (a) is a number greater than or equal to 1 and less than 10

• The exponent (n) shows how many places to move the decimal point

• Positive exponent moves decimal right, negative moves left

• Zero is written as 0 × 10⁰
