order of operations so I have a question for you what is 2 + 3 * 5 what time is it in Passaic that's some 25 2 + 3 555 + 25 not 25 cuz you broke the law the law of head order of operations you have to go in this order or else if you break the law your punishment is your answer will be incorrect so if you have to follow the mathematical law you order of operations what would you do first here you have to multiply 5 * 3 + 1515 plus 2 is 70 not 25 now this was part of one of it of a huge math problem that you had in high school later on down the road and you accidentally did this bath and you said that this was 25 and that part of your problem will be wrong we have to be careful with everything when you do order of operations now I call it the love pets some teachers College Panda and please excuse my dear Aunt whatever I pay you I don't like that term because it's misleading because we don't go in this order we don't say parentheses x phone is then multiplication then division because multiplication and division are inverse operations one is the other we either make Brew multiplication for WeChat something up in the people groups division so I like the love pets because it includes the D is for division and multiplication and the essence for subtraction in addition and how do you know what to do first addition or subtraction who's both you go left to right just like when you read Ascension you know you don't say cat my love I do you say I love my cat you go left to right so in this case you would always go left to right so anything in parentheses gets done first and then anything with exponents followed by division multiplication subtraction and addition so where would we start here the exponent 5 squared 25 now we have addition and division what would come next Division division always comes before addition and subtraction so 25 5 + 5 + 1 and you're sick what about this 1 - 15 / 3 + 7 * 5 where would you start first if you were using PEMDAS you may think I'll have to multiply first actually wouldn't matter in this case but we're going to start left to right so division -15 / 3 negative divided by a positive baby negative 5 then you have to if you started adding in the seven and a throw off your answer so you have to go to the multiplication next 5 * 735 what are we left with - 5 + 35 the answer for that one would be 30 now this one's a little tricky because you have division multiplication addition and subtraction in this case you wouldn't divide first when you have a number over number you treat them almost as if they're with their group together so you do the whole numerator the whole denominator and then solve it so let's go to the numerator what first multiplication 4 * 3 12/12 + 820 9 - 45 20 / 5 would equal 4 both important that you do the steps in order that's why it's called order of operations
