Answer:
To rewrite the expression –3 + [(–7) + (–6)] as [–3 + (–7)] + (–6) , Rashal uses associative property.
Step-by-step explanation:
Given : Rashal is adding the expression below. –3 + [(–7) + (–6)]
First, he rewrites the expression. [–3 + (–7)] + (–6)
We have to state which number property did Rashal use to rewrite the expression.
For a , b and c be integers, the following are the property under addition,
- associative property : [tex]a+(b+c)= (a+b)+c[/tex]
- commutative property : [tex]a+b=b+a[/tex]
- distributive property : [tex]a(b+c)=ab+ac[/tex]
- identity property: for 0 be the identity under addition.[tex]a+0=0+a[/tex]
Thus, To rewrite the expression –3 + [(–7) + (–6)] as [–3 + (–7)] + (–6) , Rashal uses associative property.
