  Place Value     Place value of a digit in a number is the position it occupies according to the place value chart.     Find place value of each of the digit given in number 86495. Place value of \[8\,\text{=}\,8\,\,\times \,\,\text{Ten}\,\text{thousand}\,\text{=}\,\text{8}\,\,\text{ }\!\!\times\!\!\text{ }\,\,\text{10000}\,\,\text{=}\,\text{80000}\] Place value of  \[6\,\text{=}\,6\,\,\times \,\,\,\text{Thousand}\,\text{=}\,6\,\,\text{ }\!\!\times\!\!\text{ }\,\,\text{1000}\,\,\text{=}\,6\text{000}\] Place value of  \[4\,\text{=}\,4\,\times hundred\,\text{=}\,4\,\text{ }\!\!\times\!\!\text{ }\,\,\text{100}\,\,\text{=}\,4\text{00}\] Place value of  \[9\,\text{=}\,9\,\times ten\,\text{=}\,9\,\text{ }\!\!\times\!\!\text{ }\,\,\text{10}\,\,\text{=}\,90\] Place value of \[5\,\text{=}\,5\,\times one\,\text{=}\,5\,\text{ }\!\!\times\!\!\text{ }\,\,\text{1}\,\,\text{=}\,\text{5}\]

   Face Value     Face value of a number is the number itself.   In the number 874. Face value of 8 is 8 itself. Face value of 7 is 7 itself. Face value of 4 is 4 itself.   Successor      Successor of a number comes just after the number. In other words when we add a number by 1, the resulting number is the successor of that number. Like P is a whole number, then P + 1 is successor of P.     Find the successor of 523604   Solution: 523604+1=523605 Thus 523605 is the successor of 523604   Predecessor  Predecessor of a number comes just before the number. In other words when we more...

     Number System   Number system is a pattern or set of numbers in which one number is related to other number by one or more algebraic operations. There are various number system. In this chapter we will study about the following three types of number systems:   (a) Natural number (b) Whole number (c) Integers     Natural Number Counting starts with 1 and continue till infinite. Counting numbers are called natural numbers. For example: 1,2, 3, 4, 5, 6, 7................ etc. Note: Natural number starts from 1 and goes to infinity. Therefore, smallest natural number is 1 but largest natural number cannot be found.     Whole Number When 0 is included with natural numbers, it is called whole numbers zero are called whole numbers. 0, 1, 2, 3, 4, 5, 6, more...

   Numbers     Numbers are mathematical objects by which we express date, time, distance, position, quantity, etc. for example,                                           I reached in the party at 10 o clock - time                                  My birthday is on 6th march  date.                                       Distance between the earth and the sun is 15 crore km - distance 3rd planet from the sun is the earth - position.                             There are 45 tones corn in this godown - quantity.                          We use ten symbols (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to write any number. Like 654544544, 34541540044, 35445154154454, etc.

  Introduction       Numbers can be called as the base of mathematics as mathematics starts with numbers. Therefore, understanding of numbers is essential in order to study mathematics. In this chapter we will study about the numbers, number systems and their properties.

       Introduction   Jumbled sentences are one sort of language proficiency test question.
