How do you use pemdas?

Answer 1

Well, I would recommend PMDAS.

P-arenthesis

M-Multiplication

D-Division

A-Addition

S-ubtraction

*Always remember that Multiplication and Division are equal.

*Always remember that Addition and Subtraction are equal.

Here is a PMDAS Problem that may help you.

8+2-4{-2+7-4{6x3/2+7-6]-8+10}+3

=10-4{5-4[9+7-6]-8+10}+3

Solve the numbers first in the bracket. Since we have all the operations, solve the numbers that needs to be multiplied and divided. (6x3=18 18/2=9)

=10-4{5-4[10]-8+10}+3

Now, solve the numbers from left to right which are in the bracket. (9+7=16 16-6=10)

=10-4{5-[40]-8+10}+3

In the curly brackets, we have the addition, subtraction and multiplication. So we first need to have the multiplication. (4 times 10 is equal to 40)

=10-4{-33}+3

Now, you can solve the numbers in the curly brackets from left to right because they are addition and subtraction. (5-40=(-35) (-35)-(8)=(-43) -43+10=-33)

=10-{-132)+3

Whenever you encounter numbers with two simillar signs together like, ''-{-132}'' it is considered as positive because negative times negative is equal to positive

=10+132+3

Solve the number sentence from left to right.

=145

GOOD LUCK!
