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
To solve this problem, we need to follow the order of operations (PEMDAS/BODMAS).
Step 1: Evaluate the expression inside the parentheses: 9-7 = 2.
So, the expression becomes 35 divided by (9 + 2 - 4).
Step 2: Simplify the expression inside the parentheses: 9 + 2 - 4 = 7.
So, the expression becomes 35 divided by 7.
Step 3: Perform the division: 35 divided by 7 = 5.
So, the expression is now simplified to 5.
Step 4: Now, we need to evaluate the second part: 10 times 3 = 30.
Step 5: Finally, we need to add the results from the previous steps: 5 + 30 = 35.
Therefore, the final answer is 35.
To solve this problem, we need to follow the order of operations, which is commonly remembered using the acronym PEMDAS (Please Excuse My Dear Aunt Sally).
Step 1: Simplify any expressions inside parentheses or brackets.
In this case, we have (9-7), which is equal to 2. So the expression becomes:
35 ÷ [9 + 2 - 4] + 10 × 3
Step 2: Combine like terms from left to right.
Inside the brackets, we have 9 + 2 - 4, which simplifies to 7. So the expression becomes:
35 ÷ 7 + 10 × 3
Step 3: Perform any multiplication or division from left to right.
First, divide 35 by 7, which equals 5. So the expression becomes:
5 + 10 × 3
Then, multiply 10 by 3, which equals 30. So the expression becomes:
5 + 30
Step 4: Perform any addition or subtraction from left to right.
Finally, add 5 and 30, which equals 35. Therefore, the answer to the expression is:
35
So, 35 divided by [9 plus (9-7) minus 4] plus 10 times 3 equals 35.
