How do you solve #(3\times 3- ( 2+ 1) ) \div ( 5- 2)#?
BODMAS or PEMDAS rule states the order you have to complete operations in:
Usually we start with the parentheses within the parentheses. In other words, the smallest brackets.
Now, we have two brackets. What do we do?
Remember, multiplication comes before addition or subtraction, so we complete that operation first
[note: we do not do division now, as it is an operation outside the parentheses]
Now, we have two subtraction operations. Since both are withing brackets, and both are subtraction, they are on the same level on the BODMAS scale. We do them simultaneously:
We can remove the brackets, as there are no more operations within them:
