Figure 1. Discovered by Benoit Mandelbrot around 1980, the Mandelbrot Set is one of the most recognizable fractal images. The image is built on the theory of self-similarity and the operation of iteration. In order to better understand it, we need to become familiar with a new set of numbers. Expressing Square Roots of Negative Numbers as Multiples ofi We know how to find the square root of any positive real number. √−1=i So, using properties of radicals, i2=(√−1)2=−1 We can write the square root of any negative number as a multiple ofi.Consider the square root of −49.

Time: 131 hours Free Certificate This introductory mathematics course is for you if you have a solid foundation in arithmetic (that is, you know how to perform operations with real numbers, including negative numbers, fractions, and decimals). Numbers and basic arithmetic are used often in everyday life in both simple situations, like estimating how much change you will get when making a purchase in a store, as well as in more complicated ones, like figuring out how much time it would take to pay off a loan under interest.

The subject of algebra focuses on generalizing these procedures. For example, algebra will enable you to describe how to calculate change without specifying how much money is to be spent on a purchase-it will teach you the basic formulas and steps you need to take no matter what the specific details of the situation are. Likewise, accountants use algebraic formulas to calculate the monthly loan payments for a loan of any size under any interest rate.
