What does PAMDAS satands for?

Mathematics

It's actually PEMDAS. P is for parenthesis. E is for exponents. M is for multiplication. D is for division. A is for Addition. S is for subtraction.
Here's an example that includes all of these:
(6-2)²x4/2+6-4
P first.
(6-2) = 4
(4)²x4/2+6-4
Now E.
(4)² = 16
16x4/2+6-4
Then M.
16x4 = 64
64/2+6-4
Next is D.
64/2 = 32
32+6-4
Now A.
32+6 = 38
38-4
And finally, S.
38-4 = 34.
I hope this helped

*Correction: It's PEMDAS, not PAMDAS*

P of PEMDAS = Parenthesis

E of PEMDAS = Exponent

M of PEMDAS = Multiplication

D of PEMDAS = Division

A of PEMDAS = Addition

S of PEMDAS = Subtraction

PEMDAS is to remember the precedence of the mathematical operations given above. In other words, what operation to perform first can be remembered by using PEMDAS.

Example:

3 + 4*2

As M (multiplication) comes before A (addition) in PEMDAS, therefore, first solve for multiplication of 4 and 2 and then add the resultant of 4*2 in 3:

3 + 8 (as 4*2 = 8) <--- Multiplication (M)

11 (as 3+8 is 11) <--- Addition (A)

Likewise use PEMDAS for complex expressions like (3+5)*2/3+7 by applying the precedence mentioned above.

PLEASE PLEASE HELP PLEASE

Answer:

-2 and -7

Step-by-step explanation:

This problem is about using the Factoring X.

Two numbers will multiply to the number placed at the top. These same two numbers will add to the value placed on the bottom.

Let's look at the factors of 14.

1 • 14 = 14

2 • 7 = 14

Now let's look at their sums.

1 + 14 = 15

2 + 7 = 9

We can see that 2 and 7 multiply to 14 and add to 9.

However, we need them to add to -9.

Note that two negative numbers multiplied will become positive.

-2 • - 7 = 14

Now let's look at their sum.

-2 + (-7)

Simplify the negative.

-2 - 7 = -9

We can see that -2 and -7 multiply to 14 and add to -9.

Hope this helps!
