Fractional notation is a form that non-whole numbers can be written in, with the basic form a/b. Fractional notation is often the preferred form to work with if a calculator is not available.

Writing in scientific notation involves taking a very small or very large number, converting it to an easy-to-read decimal, and raising it to a power of 10. Depending on the venue, the exponent may be expressed in various ways. However, the overall process is the same regardless of the audience.

Scientific notation is a system that helps people read either excessively large or excessively small numbers. To find the scientific notation of a number, count how many spaces the second to last digit is from the decimal point, insert a period, and represent the number as a decimalized digit term a

Multiply the constants in front, and add the exponents together when multiplying numbers written in scientific notation. Use the generic formula for the process, which takes this form: (n x 10^a) x (m x 10^b) = (nm) x 10^(a+b).

Write the orbital notation for any element by using the information on the periodic table to determine the number of electrons in each orbital. Orbitals are represented by the letters s, p, d and f.

To write a number in scientific notation form, write the digits of the original number with a decimal point after the first digit. Then write a multiplication sign, and indicate the power of 10 necessary to put the decimal point where it needs to be to express the original number.

Scientific notation word problems ask the student to perform operations with two or more large numbers. For example, if light travels at 3 x 10^8 meters per second, how far will a beam of light travel in one day?

Interval notation is used to describe what numbers are included or excluded in a set. When an arbitrary value x is greater than three but less than five, then in interval notation the set of values for x would be written as (3,5). In interval notation, parentheses denote exclusive inequalities.

To write a number in expanded form, break apart a number, and write it as the sum of each place value. For example, 8324 = 8000 + 300 + 20 + 4. Decimals may also be expanded in a similar format: 0.239 = 0.2 + 0.03 + 0.009.
