Can you cite a rule anywhere that says any calculation that looks like the distributive property of multiplication voids the normal precedence of operations in an algebraic equation?
Thanks
“Can you cite a rule anywhere that says any calculation that looks like the distributive property of multiplication voids the normal precedence of operations in an algebraic equation?”
Sister Mary Joseph’s 12 inch rule rapped across the hand. 5th grade algebra class 1950’s.
Do they still teach algebra in the 5th grade?

The Order of Operations which is 4 rules, NOT 6.
P: Simplify inside parentheses first.
E: Then apply Laws of Exponents
MD: Then multiply OR divide from left to right as it occurs
AS: Then add OR subtract from left to right as it occurs
(Too bad math textbook writers seldom know laws of arithmetic.)
The Distributive Law doesn’t apply for this expression because of the Order of Operations. The Distributive Law would apply if there was a + or - before the 2(9 + 3).
So, 48/2(9 + 3) = 48/2(12) = (48/2)(12) = 24(12) = 288
