of “Complex and Imaginary Numbers” and its applications. I chose the topic “Complex and Imaginary Numbers” because I am interested in mathematics that is hard to be pictured in your mind‚ unlike geometry or equations. An imaginary number is the square root of a negative number. That is why they are called imaginary‚ what René Descartes called them‚ because he thought such a number could not exist. In this paper‚ I will discuss how complex numbers and imaginary numbers were discovered‚ the interesting

Mean: The average (mean) number of daily visitor traffic is 3 (total amount of data adds up to 88‚ then divided this total by the number of data sets‚ 30. 88 divided by 30‚ equals 2.93‚ which I rounded up to 3.) The average (mean) number of daily sales is 1 (total amount of sales data adds up to 29‚ then divided this total by the number of data sets‚ 30. 29 divided by 30‚ equals 0.96‚ which I rounded up to 1.) Median: The average (median) number of daily visitor traffic is 3

Integers include the counting numbers (1‚ 2‚ 3‚ …)‚ their negative counterparts (-1‚ -2‚ -3‚ …)‚ and 0. ii) Whole & Natural Numbers The terms from 0‚1‚2‚3‚….. are known as Whole numbers. Natural numbers do not include 0. iii) Factors Positive integers that divide evenly into an integer. Factors are equal to or smaller than the integer in question. 12 is a factor of 12‚ as are 1‚ 2

History of imaginary numbers I is an imaginary number‚ it is also the only imaginary number. But it wasn’t just created it took a long time to convince mathematicians to accept the new number. Over time I was created. This also includes complex numbers‚ which are numbers that have both real and imaginary numbers and people now use I in everyday math. I was created because everyone needed it. At first the square root of a negative number was thought to be impossible. However‚ mathematicians soon

count how many sheep you have‚ that’s math. So when people use math‚ they didn’t know they were using it. The Romans used Roman Numerals and noticed math. So they know how to use it. That is where numbers got their name. In Babylon and Egypt‚ the people first started using theoretical tools and numbering systems. The Egyptians used a decadic numbering system‚ which is based on the number 10 and still in use today. They also introduced characters used to describe the numbers 10 and 100‚ making it easier

to represent calculations. The Chinese system is also a base-10 system‚ but it has important differences in the way that the numbers are represented. The rod numbers were developed from counting boards‚ which came into use in the fourth century BC. A counting board had squares with rows and columns. Numbers were represented by little rods made from bamboo or ivory. A number was formed in a row with the units in the right-hand column‚ the tens in the next column‚ the hundreds in the next‚ and so on
