## NCERT Solution Chapter 16: Playing with Numbers

You have studied various types of numbers such as natural numbers, whole numbers, integers and rational numbers. You have also studied a number of interesting properties about them. In Class VI, we explored finding factors and multiples and the relationships among them. In this chapter, we will explore numbers in more detail. These ideas help in justifying tests of divisibility.

Let us take the number 52 and write it as

52 = 50 + 2 = 10 × 5 + 2

Similarly, the number 37 can be written as

37 = 10 × 3 + 7

In general, any two digit number ab made of digits a and b can be written as

ab = 10 × a + b = 10a + b

What about ba? ba = 10 × b + a = 10b + a

Let us now take number 351. This is a three digit number. It can also be written as

351 = 300 + 50 + 1 = 100 × 3 + 10 × 5 + 1 × 1

Similarly, 497 = 100 × 4 + 10 × 9 + 1 × 7

In general, a 3-digit number abc made up of digits a, b and c is written as

abc = 100 × a + 10 × b + 1 × c

= 100a + 10b + c

In the same way,

cab = 100c + 10a + b

bca = 100b + 10c + a and so on.
