Step-1- Concept of commutative property and associative property of addition

The commutative property is a math rule says thatthe order in which we add numbers does not change the final product.

A+B=B+A

The associative property of addition statesthat the addition of three or more numbers remains the same regardless ofhow the numbers are grouped

A+B+C=A+B+C

02

Step-2-Evaluating given expression

48+25+22

Using order of operation,

48+25+22=48+25+22.

Using Commutative property,

48+25+22=25+48+22.

Using associative property,

48+25+22=25+22+4848+25+22=25+7048+25+22=95
