Class 6 Maths – Exercise 2.3- Question 01 to 03

(1) Which of the following will not represent zero:

(a) 1 + 0

Sol. 
= 1 + 0
= 1                                    (because any number added with 0 gives the number itself)

Here, the answer is 1. Therefore, it is not representing zero.

b) 0 × 0
Sol. 
= 0 × 0
= 0                                    (because if any number is multiplied by 0, it gives 0 only)

Here, the answer is 0. Therefore, it is representing zero.

(c)   0/2
Sol. 
= 0/2
= 0                                    (because if 0 is divided by any number, it gives 0 only)

Here, the answer is 0. Therefore, it is representing zero.

(d)   (10 – 10)/2

Sol. 
= (10 – 10)/2
= 0/2         
= 0                                (because if 0 is divided by any number, it gives 0 only)

Here, the answer is 0. Therefore, it is representing zero.
