So why isn't this equation, with 48(1/2)(9+3) distributed like that?Originally Posted by balloonoboy
Who's adding parenthesis? I was just distributing the parenthetical expressions into a binomial.Originally Posted by OptimusADL

So what would ab(c+d) be?
You cant add parentheses that aren't in the original equation.
ab(c+d) would be the same as (abc + abd)
a=48
b=1/2
c=9
d=3

since when? Multiplication and Division are done in the order that they appear, after parenthesis and exponents are doneOriginally Posted by UnkleTomCruze
Multiplication has precedence over Division, h/e the same rule doesn't apply to the addition and subtraction because they are lesser operations.
Jeezus Christ this thread is scary.
The O.g equation can also be re-written as: 48/(2(9+3)) or 48/(18+6).
Either case should result in 2 as your answer.
The two in the original equation is attached to the (9+3). You cannot separate the 2 from the (9+3).
All y'all getting 288 honestly need to commit that because we can't afford to have y'all spreading y'all genes.
288?...
...
that PEMDAS thing was a bad thing to teach because it's not completely true, unless kids remember the exceptions that go with it
not just the order of the words.
This standard is critical to simplifying and solving different algebra problems. Without it, two different people may interpret an equation or expression in different ways and come up with different answers. The Order of Operations is shown below.

Answer is two, quit debating about this. If you think it's 288, you clearly failed Algebra. Lock this up cousin.

division = multiplication of the reciprocal
subtraction = addition of a negative number
multiplication has precedence over multiplication?

You cant add parentheses that aren't in the original equation.
ab(c+d) would be the same as (abc + abd)
So following that model a/b(c+d) is the same as ((a/b)c+(a/b)d).
There are no parentheses around the b(c+d) so you should be distributing "a/b" or "1/b" not just "b".

Because it doesn't adhere to the distributive property rule. Y'all making this way too complicated.Originally Posted by IRockTMacs
