The history of the development of mathematics is a long one. No single person is given credit for the "discovery" of mathematics. As man lived in caves before any written language existed‚ he understood the nature of the first few numbers‚ the counting numbers. He could make simple comparisons and could tell that‚ say‚ 9 were more than 6. He would be able to see that if he had‚ say‚ 8 apples and there were 7 people in his group‚ each would get one and there would be one left over. This is the

The sum of any number of even numbers is always even 4. The sum of even number of odd numbers is always even 5. The sum of odd number of odd numbers is always odd 6. If N is a composite number such that N = a p . b q . cr .... where a‚ b‚ c are prime factors of N and p‚ q‚ r .... are positive integers‚ then a) the number of factors

standard one is called Pascal’s simplices. The numbers that are used in Pascal’s Triangle were numbers that were used before; he just integrated them into his invention. A simple explanation of how Pascal’s Triangle is constructed is this: “The rows of Pascal’s triangle are conventionally enumerated starting with row n = 0 at the top. The entries in each row are numbered from the left beginning with k = 0 and are usually staggered relative to the numbers in the adjacent rows. A simple construction

previously carried out Stroop effect by using numbers. A number of 180 random participants aged in between 18-89 were recruited to participate in this experiment. Participants were presented with a stroop experiment task sheet which consists of three parts which was the control‚ congruent and incongruent conditions. Time was taken and recorded for each participant to say out the number of stars in the control condition and to say out the number of numbers in the congruent and incongruent conditions

It is one of the most abstract concepts that the human mind has encountered. No physical aspects of objects can ever suggest the idea of number. The ability to count‚ to compute‚ and to use numerical relationships are among the most significant among human achievements. The concept of number is not the contribution of a single

because everyday life activities requires counting and simple calculations involving mathematical thinking. Mathematics deals with numbers comparing and computing. In modern use‚ it is termed as an abstract sign of quantity including geometry and arithmetic‚ algebra etc. The new edition of the Cambridge Learner’s Dictionary defines mathematics as the study of numbers shapes and spaces using reason and usually a special system of symbols and rules for organizing them.
