**(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**.
