The Associative Property
We discussed the use of the Associative property by re-grouping terms in paranthesis. We also used both commutative and associative properties together to help simplify expressions for evaluation.
We looked for patterns in expressions again to help speed up our mental math computation speed.
Remember, the associative property ONLY holds true for addition and multiplication. Just like the commutative property, it doesn’t work for subtraction or division.
For any numbers a, b, and c, we have in equation forms for adding and multiplication:
`a+(b+c)=(a+b)+c` and `a⋅(b⋅c)=(a⋅b)⋅c`
