What Is Standard Notation?

Standard notation writes a number in full decimal form with comma separators every three digits and a period as the decimal point, for example $4,450$ or $35,200,000$. It is the everyday way we write numbers, as opposed to scientific notation which uses a coefficient times a power of 10.

Converting Scientific Notation to Standard Form

Given $a \times 10^n$:

1. Find the exponent $n$ in the power of 10.
2. Move the decimal $n$ places right if $n$ is positive, left if negative.
3. Fill remaining positions with zeros and add comma separators.

Example: $2.7 \times 10^4 = 27{,}000$.

Worked Example

Convert $1.52 \times 10^{-5}$ to standard notation. Move the decimal 5 places left:

$$0.0000152$$
