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 ). Proof:

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

is the following; multiplication and division always produces larger and smaller values respectively. This is related to the order in which children are taught the concepts of multiplication‚ Division and extending the set of numbers from integers to non integers and fractions. Misconception | Demonstration of why this is incorrect | Multiplication always makes a number larger or it stays the same stays the samesolution larger than original number (5) | Multiplication can make numbers smaller
