Really good explanation!! I understood everything. I just don't understand why we care whether the result is negative or not...
Because when you take the square root, fourth root, sixth root, and so on your answer has to be positive.
Thank you.
why does this seems to easy
THANK YOU THANK YOU THANK YOU
You’re welcome.
THANK YOU SO MUCHH
You’re welcome.
@@crowsmathclass this helped me with my math class so I appreciate you
Thank you so much sir!
You’re welcome.
math is confirmed everywhere now
uh oh
Can you give an example (doesn't have to be practical) where this conversion is necessary? By that I mean: Is there an example where the general form "pops up" naturally (and the standard form does not)?
We want to convert so we can see the center and radius.
@@crowsmathclass That was clearly NOT my question. Please don't assume I'm stupid. But I'm looking for an example.
Thank you
You’re welcome.
This was difficult
This is just babysteps, even calculus 1-3 or more advanced maths is baby steps for chatgpt or most LLMs really. I strongly recommend you try math specialized GPTs, if you are surprised by this then youll be mindblown. I like to think about it this way, if there is a book about that topic online, chatgpt has already studied it thousands of times.
Thanks for the feedback. I will look into it.
yeah man, math GPT's are insane. I've found that some of them can even solve actuary exam questions- exams that usually take 6-8 years to pass.
Thanks a mil, you make it so easy
Thank you. Glad it helped.

Hi Prof. Crow, I am a fan and a subscriber, so I offer the following with the greatest of respect -- I am so glad that you mentioned signs of grouping symbols, because here is the real issue with these order of operations problems on UA-cam: they are using the symbol for division (the line with the two dots) instead of the actual operator for division. That's right, they are not the same thing. Division is one of the few math operations that has both a symbol and an operator. There are two, and only two operators for division: the venculum (like the line between a numerator and denominator) and the long division box. By definition, these operators function as grouping symbols also. As signs of grouping, any ambiguity as to order of multiplying or dividing is generally removed. I am guessing that the use of the symbol as an operator comes from grade school when we are first learning how to divide - and that works as long as it is understood that only the number in front of the symbol and the number immediately after the symbol are the only operands to be considered. As to the problem here, the answer is definitely 1, as malcolmtaylor pointed out. This is verified by Casio and how they treat the notation. For example, when I enter the problem exactly as written, my Casio fx-991EX Classwiz calculator will automatically put parentheses around the factor 3(2) so that it looks like this: (3(2)). This is the juxtaposition that malcolm is talking about. Here's a quote: "Latest models of EDUCATION APPROVED SCIENTIFIC CALCULATORS Like CASIO, SHARP & CANON used in board exams give higher priority to implicit multiplication or multiplication by juxtaposition." Now, if you enter the problem on the calculator using 3*(2) or 3*2, you will get the answer of 4. Even so, forget about the juxtaposition for a moment and look at the order of operations. Parentheses must be cleared before exponentiation, and both of those before doing multiplication, division, addition, and subtraction. You are absolutely correct in saying that multiplication and division are done in the order they are encountered going from left to right, but what is the first operation that you see in the problem? By order of operations rule, you have to multiply the 3 times the 2 to clear the parentheses, then you must do the exponentiation. This leaves you with 36 divided by 6 divided by 6, which results in an answer of 1. The real problem here is not the math or the order of operations; it is the syntax used in writing the problem. The syntax being used here must generate 1 as the answer because of the precedence given by implicit multiplication . Change the syntax by using explicit multiplication and it must generate the answer of 4. If anyone is interested, just enter "juxtaposition in multiplication" in a search box and you will find any number of entries that talk about and explain the idea and its precedence.
I just did a little investigation. I entered the expression in google, wolfram alpha, and on ti 30x II calculator and all of them gave me an answer of 4. I also found 2 videos with very similar problems. Links are provided below. www.google.com/gasearch?q=6%5E2/3(2)/6&source=sh/x/gs/m2/5#fpstate=ive&vld=cid:4f73abd2,vid:tvjJppmx9Hk,st:0 www.google.com/gasearch?q=6%5E2/3(2)/6&source=sh/x/gs/m2/5#fpstate=ive&vld=cid:fdd744f0,vid:gBd-qYaEWq8,st:0
@@crowsmathclass Yes, I get the same answer of 4 on my TI. Only Casio and the others that are mentioned in my quote seem to pay any attention to the change. By the way, I very much enjoyed your series of videos on applied calculus - you're a great teacher!
Thank you.
The video is wrong. Multiplication by juxtapostions takes precedence over other forms of multiplication and division.
Answer is 1 Get rid of brackets first Then it becomes 36/6/6/=1 No two ways about it
This video is a waste of time. It doesn't address the source of the controversy and declares an answer (because I say so). The source of the controversy is that different people use different conventions. The SOLUTION is to understand that it may be ambiguous and write the question more clearly. Personally I feel that the answer is 1, and I think that most people who do a graduate level degree in math/physics/engineering would agree. Here are three videos that actually teach you something rather than just spreading more confusion. ua-cam.com/video/lLCDca6dYpA/v-deo.htmlsi=EiaMkC92SJYZEhOD ua-cam.com/video/4x-BcYCiKCk/v-deo.htmlsi=2S8YyB2c0GPftMve ua-cam.com/video/Q0przEtP19s/v-deo.htmlsi=ioZYUHrSgI5HleyX
Wrong go back to school and learn that 3(2) is considered a single term whereas 3x(2) is 2 terms
You would be incorrect
@@crowsmathclass Perhaps you should do the topic justice and delve into the nuance like some other well researched videos. ua-cam.com/video/lLCDca6dYpA/v-deo.htmlsi=EiaMkC92SJYZEhOD ua-cam.com/video/4x-BcYCiKCk/v-deo.htmlsi=2S8YyB2c0GPftMve ua-cam.com/video/Q0przEtP19s/v-deo.htmlsi=ioZYUHrSgI5HleyX I disagree with your answer, and think people with degrees in math/physics/engineering would too. The real problem is that the question is ambiguous since the convention is so heavily disputed. And your video only adds to the confusion rather than resolving it.
@@crowsmathclass He would be correct. You would be incorrect.
@@crowsmathclass No, YOU would be incorrect.
Answer is 4

Isn't it normal to do parantheses first?
Parentheses used as grouping symbols. The parentheses in this problem represent multiplication.
not in this case. it is not a grouping there. it is just a simple multiplication.
@@pandadrumming Except it IS a use of parentheses. if they had wanted to represent it as multiplication, they would have. Mathematics is not a game, it is a precise use of numbers and variables with specific sets of operators (and other symbols) to represent the types of actions to be performed.
