This would be the associative property of addition because it states "for all real numbers a,b and c their sum would be the same regardless of their grouping."
So, %28a%2Bb%29%2Bc=a%2B%28b%2Bc%29
In your equation %288.9%2B2.4%29%2B7.6=8.9%2B%282.4%2B7.6%29
%2811.3%29%2B7.6=8.9%2B%2810%29
18.9=18.9
Associative property of addition
