How do you answer pemdas?

Answer 1

PMDAS

P-Parenthesis

E-Exponents

M-Multiplication

D-Division

A-Addition

S-Subtraction

*Remember that Multiplication and Division are equal.

*Remember that Addition and Subtraction are equal.

Here are some of the examples that may help you.

1. 5-2{-4+7[-2+(12/4)-6x4]+5}

=5-2{-4+7[-2+(3)-6x4]+5}

Solve the numbers in the parenthesis.

=5-2{-4+7[-2+3-24]+5}

Multiply first 6x4 since it is multiplication.

=5-2{-4+7[-23]+5}

Since all of the operations in the square bracket are addition and subtraction, solve it from left to right. (-2+3=1) (1-24=-23)

=5-2{-4+[-161]+5}

Then, solve the numbers in the curly brackets. First, solve the numbers that needs to be multiplied (7 times -23 is equal to -161).

=5-2{-160}

Now, the operations in the curly brackets are addition and subtraction. Solve them from left to right. (-4+(-161)=(-165) -165+5=(-160)

=5-(-320)

As you can see we have two operations, subtraction and multiplication. So we must first solve the multiplication(2 times -160 is equal to -320).

* Whenever you encounter numbers which has two similar signs just like ''-(-320)'' it is considered as positive. ''+320''

=5+320

We changed the -320 to positive.

=325

The answer is 325.
