Standard Form (scientific notation): Expresses large or small numbers in the format $a \times 10^n$, where $a$ is between 1 and 10. This simplifies calculations with extreme values.

Converting to Standard Form: Move the decimal point to make a number between 1 and 10. For example, 26,000 becomes $2.6 \times 10^4$ by moving the decimal 4 places.

Multiplying Numbers in Standard Form: Multiply the coefficients and add the exponents. For instance, $(2 \times 10^7) \times (8 \times 10^{-12})$ simplifies to $16 \times 10^{-5}$. But be careful, you need to adjust the result to be $1.6 \times 10^{-4}$.
