Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

Suppose a, b, and c is three real numbers.

Associative property of Addition: (a + b) + c = a + (b + c)

If you are adding three real numbers, the sum is always the same regardless of their grouping.

Example: (11+12) + 13 = 11 + (12+13) = 36

Associative property of Addition states, if you are adding three real numbers, the sum is always the same regardless of their grouping.

Name of the property for this equation 4 + (3 + 9) = (4 + 3) + 9 is Associative property of Addition.

According to the above property, we can evaluate the expression:

$\begin{array}{l}45+29+55\\ 45+(29+55)(\text{AssociativePropertyofAddition)}\\ \text{(45+29)+55}(\text{AssociativePropertyofAddition)}\\ \text{74+55=129}\end{array}$

$45+29+55  =129$
