Multiplication: To multiply numbers in scientific notation, **multiply the decimal numbers.** **Then add the exponents of the powers of 10.** **Place the new power of 10 with the decimal in scientific notation form**.

## How do you do addition in scientific notation?

Quote from the video:

Youtube quote: *And now since the powers were the same all I do is bring this power down 10 to the fifth. And use it my final answer simple is up so my answer is seven point nine seven nine. Times ten to the fifth.*

## How do you multiply scientific notation with scientific notation?

Since all number in scientific notation have base 10, we can always multiply them and divide them. To multiply two numbers in scientific notation, **multiply their coefficients and add their exponents**. To divide two numbers in scientific notation, divide their coefficients and subtract their exponents.

## How do you multiply scientific notation examples?

Quote from the video:

Youtube quote: *Examples let's multiply 8 times 10 to the 5 by 7 times 10 to the 6. So first we need to multiply 8 by 7. And just as before we need to add 6 8 times 7 is 56 and 5 plus 6 is 11.*

## How do you do scientific notation in math?

A shorthand method of writing very small and very large numbers is called scientific notation, in which we express numbers in terms of exponents of 10. To write a number in scientific notation, **move the decimal point to the right of the first digit in the number**. Write the digits as a decimal number between 1 and 10.

## How do you multiply a whole number by scientific notation?

**Multiply the whole number by the coefficient of the number in scientific notation**. For example, if you want to multiply 2.5 * 10^3 by 6, multiply 2.5 by 6 to get 15.

## How do you solve scientific notation equations?

To convert to scientific notation, **start by moving the decimal place in the number until you have a coefficient between 1 and 10**; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
