Let us now find 4 2´ . NOTE
Method : Starting from 0, jumping 2 units at a time, to the right, make 4 such 4 × 2 (means 4 times)
moves.

0 1 2 3 4 5 6 7 8 9 10
Hence, 4 2´ = 8

EXAMPLE 1. State which of the following number lie on the right of the other number on the number
line?
(a) 567 and 235 (b) 985231 and 966510

SOLUTION : (a) Clearly, 567 > 235
\ 567 lies to the right of 235.

(b) Clearly, 985231 > 966510
\ 985231 lies to the right of 966510.
EXAMPLE 2. Using number line, find the following:
(a) 2 3+ (b) 6 2- (c) 3 3´

SOLUTION : (a) 2 3+

0 1 2 3 4 5 6 7 8

(b) 6 2-

0 1 2 3 4 5 6 7 8

(c) 3 3´

0 1 2 3 4 5 6 7 8 9 10

Exercise 2.1

1. Say True (T) or False (F):
(a) Zero is the smallest natural number.
(b) All the whole numbers are natural number.
