In this method, the index number is equal to the sum of prices for the year for which index number is to be found divided by the sum of actual prices for the base Using an index or power. Here is a number written in index form: Example of how to write numbers in index form. Base number shown as 2 and. 2 is the base Mathematics IMA. Intro. to Fin. Maths I. Index laws are the rules for simplifying expressions involving powers of (2) Watch out for powers of negative numbers. In many applications of mathematics, we can express numbers as powers of some given base. We can reverse this question and ask, for example, 'What power a mathematical notation indicating the number of times a quantity is multiplied by itself. index(noun). an alphabetical listing of names and topics along with page 11 Dec 2014 Watch this video lesson to learn what index numbers are. in secondary education and has taught math at a public charter high school.

### index is the same as power The index of a number say how many times you have to use the number in a multiplictaion. e.g; 2 10 = 10*10=100

In mathematics and computer programming, index notation is used to specify the elements of an array of numbers. The formalism of how indices are used varies according to the subject. In particular, there are different methods for referring to the elements of a list, a vector, or a matrix, depending on whether one is writing a formal mathematical paper for publication, or when one is writing a computer program.

What are index numbers? Index numbers are a useful way of expressing economic data time series and comparing / contrasting information. An index number is a figure reflecting price or quantity compared with a base value. The base value always has an index number of 100. The index number is then expressed as 100 times the ratio to the base value.
