Explain how the order of operations shows how to simplify an experession. how does pemdas work into this? what does pemdas stand for? be sure to explain the rules for addition, subtraction, multiplication, divison, and the use of grouping symbols. use examples to illustrate your points.

PEMDAS is an acronym, meant to help solve an expression with multiple actions.

It stands for Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction.

You always simplify after solving an action, and you always read from left to right.

the order of operations shows us the proper sequence in answering/simplifying an expression.

Step-by-step explanation:

PEMDAS stands for Parenthesis(do first), Exponents,(second),Multiplication(do third, Division(do fourth), Addition(do fifth), and subtraction(do last) when multiple of soemthing always go right to left.

PEMDAS can be remembered by Please Excuse My Dear Aunt Sally.

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72

i use my brain for prombles like this maybe you could try it
