insufficient to argue that a mathematical statement is true simply by experiments and observations. For instance‚ Fermat (1601–1665) conjectured that when n is an integer greater than 2‚ the equation x n + y n = z n admits no solutions in positive integers. Many attempts by mathematicians in finding a counter-example (i.e. a set of positive integer solution) ended up in failure. Despite that‚ we cannot conclude that Fermat’s conjecture was true without a rigorous proof. In fact‚ it took mathematicians

facilitated students to solve small programming problems assignments. This technique; identifies the steps involved in each process to be performed and the inputs to and outputs from each step. However‚ this technique lacks the proper procedures to identify the root or roots of the problem. Therefore‚ this technique leaves the student without the understanding of what the problem is and what is really causing it [3]. In the real world computer or programming analysts are confronted with more complicated

challenging. Although there is no fixed set of rules for practicing‚ you might try working each batch of problems under standard AIME conditions. Essentially‚ that means no calculators are allowed‚ the testing period is 3 consecutive hours‚ all answers are integers from 000 to 999 inclusive‚ and there are no penalties for guessing. An appoximation of the cover of the actual AIME phamphlet preceeds each problem set1 ; the cover will list the official testing parameters‚ including any slight changes from past

the subproblems don’t have to be 1/2 the size of the parent problem. We then get the following theorem‚ our first version of a theorem called the Master Theorem. (Later on we will develop some stronger forms of this theorem.) Theorem 5.1 Let a be an integer greater than or equal 1. Let c be a positive real number and d a nonnegative form aT (n/b) + nc T (n) = d then for n a power of b‚ 1. if logb a < c‚ T (n) = Θ(nc )‚ 2. if logb a = c‚ T (n) = Θ(nc log n)‚ 3. if logb a > c‚ T (n) = Θ(nlogb a ).

shows a notable difference. Secondly zero is a number itself which we use in the form of 0 (Robertson‚ 2000). Zero is the smallest whole number. The whole numbers greater than zero are called positive integers‚ whereas‚ the whole numbers less than zero are referred to as negative integers. Zero is an integer itself but it is neither positive nor negative. Therefore‚ in early times‚ the concept of zero was the harder to accept than negative numbers as people were aware of the loss and debt which is a negative

previous lessons‚ the students had learned about positive and negative integers. Using concrete and realistic situations‚ the students were able to understand the concept and were now ready to learn about adding and subtracting integers using algebra tiles. This would eventually allow the students to be able to solve simple equations‚ with and without the algebra tiles. However‚ the students were able to learn how to add integers conceptually while using the tiles first. This becomes even more important
