NUMBERS AND OPPERATIONS

 Real numbers system

  • These are the set of all counting numbers such as 1,2,3,4,5,6,7,8,9, ......
  • Real numbers are numbers that include both rational and irrational numbers. Rational numbers such as integers (-3, 0, 2), fractions (1/2, 3.5) and irrational such as √3 ,ฯ€(22/7), are all real numbers
  • NB: 1.  Under Integers there's negative numbers (-1; -2...) and whole numbers (0;1;2;3....)
                  2. Under Whole numbers there's Natural numbers (1,2,3). Remember that 0 is not a natural                             number.
                  3. Under Natural numbers there's Prime numbers (2;3;5;7......) and Composite number                                     (4;6;8;9....).
  1. May you please study this picture its more clearly emphasized about real numbers


EXAMPLES

  • From the list bellow identify Negative, Whole, Irrational, Prime and Composite numbers               -3, 2, 4, 7, ฯ€, 0
Negative number = -3
whole numbers = 0, 2, 4 & 7
Irrational numbers = ฯ€
prime numbers = 2 & 7
Composite numbers = 4

Sequences

  Sequences A sequence is a list of numbers in a specified order. The different numbers occurring in a sequence are called the terms of the sequence. Let the terms of a sequence be a 1 , a 2 , a 3 , …, a n , …, etc. The subscripts indicate the position of the term. That means, First term = a 1 Second term = a 2 Third term = a 3 …. The nth term is the number at the nth position of the sequence and is denoted by a n . This term is also called the general term of the sequence. Sequences Rules All the terms of a sequence possess a certain rule upon which the successive terms are defined. In the above examples, the sequence 3, 9, 27, 81…,59049 indicates the rule as the powers of 3. Here, each succeeding number will be obtained by multiplying the previous term with 3. Similarly, the set of even numbers also contains a rule that each successive term is obtained by adding 2 to the previous term. Based on these rules, we can define the general term of the sequences. This can be done as give...
