35 divided by [9 plus (9-7) minus 4]

plus 10 times 3..can someone please
explain how to do this problem

think of "Please Excuse My Dear Aunt Sally"
P is for paranthesis first
E is for exponents
M and D are for multiply and divide, they go in order as whatever comes first from left to right whether its multiply or divide
A and S are for adding and subtracting. same as with multiply and divide they go in the order they appear on the problem
from left to right

I know that I just don't know how to
break it down or the answer.
must be beyond me the teacher gave it
to us for homework for extra credit
and we never did anything like it
before

Like Evan said you have to do it in the order above. Start with the parenthesis and work from there. Just try it. We can check it for you.

35 is answer i guess

To solve the given problem, let's break it down step by step using the order of operations (PEMDAS).

Step 1: Start by simplifying the expression inside the square brackets.

9 plus (9-7) minus 4
First, solve the subtraction inside the parentheses:
9 - 7 = 2
The expression becomes:
9 plus 2 minus 4

Step 2: Continue simplifying the expression inside the square brackets.

9 plus 2 minus 4
Next, perform the addition:
9 + 2 = 11
The expression becomes:
11 minus 4

Step 3: Simplify the expression inside the square brackets.

11 minus 4
Now, perform the subtraction:
11 - 4 = 7

Step 4: Solve the remaining operations outside the square brackets.

35 divided by 7 plus 10 times 3
To continue with the PEMDAS order of operations, start with multiplication:
10 times 3 equals 30

The expression becomes:
35 divided by 7 plus 30

Now, perform the division:
35 divided by 7 equals 5

The expression becomes:
5 plus 30

Finally, perform the addition:
5 plus 30 equals 35

So, the final answer is 35.
