## How do you do scientific notation with operations?

Youtube quote: *Remember the powers of 10 will add if dividing. The power to pairs of 10 we'll subtract. After you get your answer make sure the decimal only has one digit in front to keep it in scientific notation.*

## What are the 4 rules of scientific notation?

Scientific Notation Rules

**The absolute value of the coefficient is greater than or equal to 1 but it should be less than 10**. Coefficients can be positive or negative numbers including whole and decimal numbers. The mantissa carries the rest of the significant digits of the number.

## How do you apply arithmetic with numbers written in scientific notation?

When multiplying two numbers in scientific notation, you can **multiply the two significant digit figures and arrive at a power-of-ten by adding exponents**. When dividing two numbers in scientific notation, you can divide the two significant digit figures and arrive at a power-of-ten by subtracting exponents.

## How do you solve an equation using scientific notation?

Quote from the video:

Youtube quote: *So we need to multiply. By 10 to the third and once again we have two exponents with the same base that are being multiplied. So we can simplify this by adding the exponents. So we have one point zero*

## How do you write scientific notation?

The proper format for scientific notation is **a x 10^b** where a is a number or decimal number such that the absolute value of a is greater than or equal to one and less than ten or, 1 ≤ |a| < 10. b is the power of 10 required so that the scientific notation is mathematically equivalent to the original number.

## Why is it important to apply scientific notation in some laboratory activity?

The primary reason why scientific notation is important is that **it allows us to convert very large or very small numbers into much more manageable sizes**. When these numbers are in scientific notation, it is much easier to work with them.

## What is the application of scientific notation used for?
