45 3 2 What is counted first and then what?

According to the rules of operation, this formula should first calculate the addition in parentheses, first calculate the sum of 3+2, the result is equal to 5, and then calculate the subtraction outside the parentheses, 45-5, the result is equal to 40

There are parentheses, first count the addition in the parentheses, 3+2=5 45-5=40. That's how it counts. If there are parentheses, the formula within the parentheses is counted first, and then the formula outside the parentheses.

This equation first calculates 3+2 in parentheses, and then calculates the sum of 45-(3+2).

Of course, it is to do the inside of the brackets first, and then calculate the outside of the brackets, which is equivalent to making the inner answer equal to five first, and then 45 and subtracting five to equal 40

There are additions and subtractions, as well as parentheses, so you have to calculate the addition in the parentheses first, and then subtraction, so you have to calculate 3+2=5 first, and then 45-5=40.

According to the mathematical application algorithm, there are parentheses and the brackets are counted first, so first calculate 3+2 and then use 45 to subtract three plus two.

There are parentheses and the inside of the brackets is a very certain thing. So you have to count the 3+2=5 in parentheses first. Then use 45 on the outside and subtract the total number in parentheses to equal 40.

Count the ones in parentheses first, so add first and then subtract, and the result is 40

The addition of the numbers in parentheses is calculated first, and then subtracted.

Count the addition in parentheses first, then the subtraction.
