Step by step solution

01

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 states that the addition of three or more numbers remains the same regardless of how the numbers are grouped,

A+B+C=A+B+C.

02

Step-2-Evaluating given expression

16+18+14

Using Order of operations,

16+18+14=16+18+14.

Using Commutative property,

16+18+14=18+16+14.

Using associative property,

16+18+14=18+16+1416+18+14=18+3016+18+14=48

03

Step-3-Conclusion

Therefore, the value of given expression is 48.
