modern meaning of probability‚ which‚ in contrast‚ is used as a measure of the weight of empirical evidence‚ and is arrived at from inductive reasoning and statistical inference. A short history of Probability Theory............ The branch of mathematics known as probability theory was inspired by gambling problems. The earliest work was performed by Girolamo Cardano (1501-1576) an Italian mathematician‚ physician‚ and gambler. In his manual Liber de Ludo Aleae‚ Cardano discusses many of the basic

Zero in Mathematics Zero as a number is incredibly tricky to deal with. Though zero provides us with some useful mathematical tools‚ such as calculus‚ it presents some problems that if approached incorrectly‚ lead to a breakdown of mathematics as we know it. Adding‚ subtracting and multiplying by zero are straightforward. If c is a real number‚ c+0=c c-0=c c x 0=0 These facts are widely known and regarded to hold true in every situation. However‚ division by zero is a far more complicated

of any circle’s circumference to its diameter in the Euclidean plane; this is the same value as the ratio of a circle’s area to the square of its radius. It is approximately equal to 3.14159265 in the usual decimal notation. Many formulae from mathematics‚ science‚ and engineering involve π‚ which makes it one of the most important mathematical constants. π is an irrational number‚ which means that its value cannot be expressed exactly as a fraction m/n‚ where m and n are integers. Consequently

Zero is a number and a digit used in mathematics to represent that number in numerals. Zero is not a natural number but it is the smallest whole number. There are two important uses of zero. Firstly‚ in place value number system it is used as empty place indicator. Hence‚ in this number‚ 5102‚ the positions of 5 and one are correct just because of the inclusion of zero. Five is denoting a thousandth place value. Similarly if we omit zero from 5102 that is 512‚ then 5 denote a hundredth place value
