31. $[5 + (- 2)] + (- 4) = 5 + [- 2 + (- 4)]$

Short Answer

Expert verified

Name of the property illustrated isAssociative Addition.

Step by step solution

- Write properties of real numbers

Properties of real numbers are written in following table:

For any real numbers $a, b,$ and $c :$
Property	Addition	Multiplication
Commutative	$a + b = b + a$	$a 路 b = b 路 a$
Associative	$(a + b) + c = a + (b + c)$	$(a 路 b) 路 c = a 路 (b 路 c)$
Identity	$a + 0 = a = 0 + a$	$a 路 1 = a = 1 路 a$
Inverse	$a + (- a) = 0 = (- a) + a$	If $a 鈮� 0$ , then $a 路 \frac{1}{a} = 1 = \frac{1}{a} 路 a$
Distributive	$a (b + c) = a b + a c and (b + c) a = b a + c a$

- Substitution in given values

Substitute a for 5, b for $- 2$ and c for $- 4$ in given equation.

Now equation becomes $(a + b) + c = a + (b + c)$

- Identify the property

From the table of properties of real numbers, $(a + b) + c = a + (b + c)$ is the property of associativity in addition

Thus, associative addition is illustrated by given equation.
