We have to solve the above expression.

• As we know, adding two or more numbers together is known as an addition.
• The addition is denoted by a symbol(+).

Following are the properties of addition:  

1. Identity property of zero.  

2. Inverse property.

3. Commutative property.

4. Associative property.

We are solving in the following way:

We have,

$11+11+11+11+11+11+11+11+11$
