How do you turn a number in standard form into a number in scientific notation

"A standard number larger than 1 can be converted to scientific notation by increasing the power of ten by one for each place the decimal is moved to the left."

Explanation:

"The number -6,000,000,000 could be written in scientific notation as -6x10 9. The number -6,000,000,000 is equivalent to -6*1,000,000,000."

You move the decimal to the left until the whole number is one digit.

If the number is a decimal, move the decimal to the right until it is one digit, the exponent will be negative.

For example:

123456. ---->1.2345*10^5

The 5 comes from moving the decimal 5 spaces to the left

.00012345 --->1.2345*

The -4 comes from moving the decimal exponent 4 spaces to the right.
