Question

1. Use a letter for 'any number' and write the following properties in short. (1) The sum of any number and zero is the number itself. (2) The product of any two umbers and the product obtained after changing the order of those numbers is the same. (3) The product of any number and zero is zero. 2. Write the following properties in words : (2) n+1 (1) m-0-m​

Answer 1

Answer:

1.

(1)$t + 0 = 0$

(2) $(x)(y) = (y)(x)$

(3) (r)0 = 0

2.

(1) n is added to 1

(2) m minus 0 minus m

Step-by-step explanation:

Answer 2

Answer:

1) $n+0=n$

2) $n$ × $m$ $=m$ × $n$ =  $n$$m$

3) $n$ × $0=0$

Step-by-step explanation:

Let $m,n$ be any two numbers.

1) The sum of any number and zero is the number itself.

⇒ $n+0=n$

2) The product of two numbers is $n$ × $m$.

And product of numbers after changing the order is $m$ × $n$.

Thus,  $n$ × $m$ $=m$ × $n$ =  $n$$m$.

3) The product of any number and zero is zero.

⇒ $n$ × $0=0$

1) $n+1$

Then, the sum of any number $n$ and one is the number greater than $n$.

2) $m-0=m$

The difference of any number and zero is the number itself.
