Solve either of these questions, dumass:

12x² y ÷ 4x + (6x – x)²

{4 [2xz^4 (2c³v ÷ 2cv²)³ ÷ 2]} ÷ c^6x • v³ = 4z^4 = ??

Variables
In algebraic expressions, letters represent variables. These letters are actually numbers in disguise. In this expression, the variables are x and y. We call these letters "variables" because the numbers they represent can vary—that is, we can substitute one or more numbers for the letters in the expression.
Quoting: math.com

God you know absolutely nothing about math, let alone the equation at hand. You can't solve THIS equation, nor any of the other ones I gave you... you don't know the identity law, the distributive property, or what a variable is. Who failed grade 3 ????

But, this was not taught to people this way before the seventies, because I know people in their 60s and 70's will disagree to the grave on how to do this.

It's just basic math. You don't have to believe me if you don't want to.

I'll put this here:

It’s important to note that not all calculators handle the order of operations in the standard way.

Because the equation is
6 ÷ 2(2+1) = 3/(2+1) = 1

THAT's how.

6 ÷ 2n = 3/n. Ask your stupid wolfram if that is true. n = 2+1

Wolfram, and everyone other calculator doesn't know how to substitute variables with values.

It knows 2n/2n = 1
6/2n = 3/n

But when you try and fill a value in, it throws up. Therefore, if you can't do algebra, let wolfram do it for you, then when it simplifies the equation for your dumbass, fill in 2+1.

6 ÷ 2n = 3/n

n = 2+1

6 ÷ 2(2+1) = 1

This:

is just plain wrong. you don't get an extra division just because you want to, okay.

Re: Math: 6÷2(1+2) = ?
0_o what is happening to you people that you can't figure out the simple rule of PEDMAS?

First we work parentheses:

6÷2(3)

The only reason the parenthesis stays is so that we know we have a multiplicative relationship between 2 and 3, otherwise it would have been removed.

To continue on, we then move on to multiplication/division. Since we have division first from left to right, we work it out first:

3(3)

then work this out and the answer is 9.

Distributive Property:

"We use the distributive property to help us find a way around the order of operations while still being sure that we keep the value of the expression."

Distribute BEFORE "pedmas" to REMOVE parentheses [link to www.algebra.com]

Get Rid of parentheses with Distribution:

"When simplifying expressions with parentheses, you will be applying the Distributive Property." -purplemath

The Distributive Property in ALgebra:
The Distributive Property is handy to help you get rid of parentheses.
a(b + c) = ab + ac

These guys got it right, they use "Parentheses" in the order of operations to require Distributive Property.
Ref: Purplemath

Example of parentheses:

"Whatever is enclosed in parentheses must be simplified first, or if not, it must interact as a quantity with anything outside. This means any operation on the quantity in parentheses must be applied to all of its parts. The most common and important example is called the distributive property." -holytutoring

If there is some factor multiplying the parentheses, then the only way to get rid of the parentheses is to multiply using the distributive law.

Distributive property CAN be used with numbers.: [link to louisacounty.va.schoolwebpages.com]

NO. You absolutely REQUIRE ( ) around the 6 ÷ 2.

Derivation:
6 + 3 = 9
Now factor out 6/2:
(6/2)2 + (6/2)1 = 9
(6/2)(2+1) = 9
(6 ÷ 2)(2 + 1) = 9

Fractional Coefficients require parentheses if they use a '/'

no they don't, / is the same as divide symbol. so for mutiply and divide, you go left to right.

6/2 * (1+2)

could be written as:

a * b

where:

a = 6/2
b = (1+2)

the bizarre bit is that some people would rather write it as a/b for some reason. it is clearly multiplication, not division.
