# How To: Use algebra scientific notation and standard form

In this video we will learn about algebra SCIENTIFIC NOTATION and STANDARD FORM. Watch the above math video to learn how to change large numbers from standard form to scientific notation.

To change a whole number that is greater than one from standard form to scientific notation:

• Copy all the nonzero digits and the zeros that are between nonzero digits (if there are any).
• Place the decimal point after the first nonzero digit.
• Multiply this number by a certain power of ten.
• To determine the exponent, simply count all the digits that are after the first nonzero digit in the standard form.

To change a positive decimal that is less than one from standard form to scientific notation

• Copy all the nonzero digits and the zeros that are between nonzero digits (if there are any).
• Place the decimal point after the first nonzero digit.
• Multiply this number by a certain power of ten.
• The exponent is a negative number.
• To determine the exponent, simply count all the digits that are between the initial position of the decimal point, and the first nonzero digit in the standard form. In the scientific notation, place the result of your counting at the exponent with a negative sign in front of it.
