Question: 48+2(9+3)-? A: 2 B: 288 Answer: "" is NOT descriptive Does it mean the last term in the numerator or the denominator? Denominator Numerator The problem 2 (9+3) = 288 | | is with the "." symbol! They are NOT the same! Hint: Use the "" symbol or brackets. It is more descriptive.
Best Answer - Chosen by Voters atics is supposed to provide you with single, definitive answers. However, in Mathem this case, it does not. I really scoured the internet and countless textbooks for the Phyxiusproper answer and have made inquiries with few people I know whom I venerate as AEnimus some of the greatest minds that I have had the luxury of meeting and the answer isn't as definitive as you would hope. Sadly, the real answer is that both sides are correct to a point. (...and it pains me to even remotely admit that anything outside of 288 could be the answer). Position 1: The Order of Operations: This stance states that since the standard order of operations puts multiplication and division on the same rank, the equation can be read as (48 2)(9+3). This reigns with truth as 48+2(9+3) is the same as 48+2*(9+3). Using the standardized left-to-right notation, the answer can be nothing outside of 288. This left-to-right concept is indicative of "PEMDAS" that we all learned in grade school Position 2: The Distributive Property: This stance states that multiplication through juxtaposition, being a commonplace concept, naturally makes a parenthetical implication around grouped numbers. Thus, the equation appears as 48+[2(9+3)]. This technique is correct as well. However, this mak es the answer 2.
