[tex]The \ Associative \ Property \ is \ the \ rule \ that \ refers \ to \ grouping.\\ For \ addition, \ the \ rule \ is: \\\\ a + (b + c) = (a + b) + c \\\\ 2 + (3 + 4) = (2 + 3) + 4 \\\\2+7=5+4\\\\9=9[/tex]
[tex]For \ multiplication, \ the \ rule \ is :\\\\ a(bc) = (ab)c \\\\ 5(7 \cdot 8) = (5 \cdot 7)8\\\\5\cdot 56=35\cdot 8\\\\280=280[/tex]
