Bracket first. Inside the brackets: (1) divide 16/2=8. (2) multiply 8x2=16. (3) add 16+4=20. (4) multiply 20x3=60. Always follow this criteria. Easy.

Solved it at the thumbnail, the answer is a) 60 0) 3 ( 4 +16 / 2 * 2 ) -- starting condition 1) 3 ( 4 + 8 * 2) -- inside the Parentheses, do the first multiplication or Division parsing left to right. 2) 3 ( 4 + 16 ) -- Continue with the next Multiplication or division in the parentheses. 3) 3 ( 20 ) -- Perform the Addition. 4) 60 -- finish with the multiplication outside the parentheses. Done.

Any body can answer me.....when fid pemdas started to be used bcaus in high sch I learnt 'multiplication' 1st then división then addition then subtraction. In the mid to late 1980,s any body had this taught to them

@dazartingstall6680 9 ай бұрын

That might be what you remember, but I guarantee that it's not what you were taught. The order of operations has always treated multiplication and division as having equal priority. Basically, because they're the same operation: division is simply multiplication of the reciprocal. (Ditto addition and subtraction.) FYI, I was taught this in the late 1970's.

@bigdog3628 6 ай бұрын

super simple we got the first two steps as division and Multiplication by the same number so we ignore it and the number to the left of the set is what we want. this case 16. so 16 +4 is 20 * 3 is 60 .

@dazartingstall6680 9 ай бұрын

That's actually a pretty bad example. With this particular problem, provided you remembered to do brackets first, you'd still get the correct answer if you completely forgot the rest of the order of operations and just worked left to right: 3(4+16÷2×2)= 3(20÷2×2)= 3(10×2)= 3(20)=60

This is one of those instances where it's just syntax. Unfortunately, we have a bunch of dunces who learn that, and then think Math's subjective. It's like, no it's not... it's just a language we use. And like all language, to communicate something, there has to be a basis in reality. Just for some reason, we don't understand context is important in math, as much as it is in writing. Because some mathematicians might write that where the multiplication is done under the divisor. And it's like, well that'd be correct, only if there's a workable problem where that'd be needed. So, generally, this is like solving vacuous logic puzzles, like "If all pizzas are stones, and some stones are houses, what can be concluded from this?" It's like, math and language isn't understood in that way. Sure, you can derive some system of knowledge with it, but more practically, things in logic and algebra have to be applied to something contextual, in order for it to have real meaning.

@thomasharding1838 2 ай бұрын

Nothing can be CONCLUDED from that. Nothing says ALL Stones are Pizzas. You might ASSUME that SOME houses are PIZZAS but you cannot conclude that even that is a fact.

@BKNeifert 2 ай бұрын

@@thomasharding1838 I don't even know what you're saying. Houses aren't pizzas. Period. So, I don't know if you're using some vacuous logic puzzle, but context speaks everything. A house is not a pizza, so that whole point is moot. And whatever thing the class happens to be doing at that time, it's what the project is about. Like, say you build a house out of pizza--like a gingerbread house--then that's a thing of its own. It fits to its context, and whatever use or purpose it has.

It is unfortunate that this example comes up with the correct answer even when you do it in the wrong order. I’ll add parentheses to emphasize the two different methods. First the wrong order: 3*(((4+16)/2)*2)=60, as does the correct order of operations 3*(4+((16/2)*2))=60
