Number Play 55

INTRODUCTION
Number is a basic component of Mathematics. Numbers are used in different-different ways to organise our work,
our lives etc. Numbers are used for counting, measuring, keeping things in order, indexing and many more by
applying the basic operations like addition, subtraction, multiplication and division on them.

With the help of this chapter, we will carry on this journey by playing with numbers, by seeing numbers around
us, seeing patterns and to use the operations in new ways.

CLASSIFICATION OF THINGS BY USING NUMBERS
Classification can be defined as the arrangement or sorting of objects into groups on the basis of a common
property that all of them have. It refers to the process of categorizing objects or numbers into distinct groups or
classes based on their characteristics.
We can classify numbers or figures on the basis of various parameters depending on the object we are dealing with.
Let’s discuss a few ways to understand this

(i) Classification of objects by their height (a number)
We can classify people based on their height.

(ii) Classification of objects by their counting (a number)
We can also classify or arrange the given set of objects based on the number of objects present.

SUPER CELLS
Basically super cell is a type of block of number and this number is larger than its adjacent cells. Cells means
those cells which are situated around (left, right, top, bottom) super cell.
With the help of following structure, we can easily understand this.

Cell - 4(d)

Cell - 2(b) Super cell (m) Cell - 1(a)

Cell - 3(c)

Here, m, a, b, c, d are the numbers of any digit.
But, according to the concept of super cell
m > a, m > b, m > c, m > d
Now observe the numbers within in the table below:

61 41 49 16 17
65 76 35 26 9
