Thanks leslie. This language has always confused me. That makes sense. I think i was thinking of camparing place value. Earlier place values of the number are at the beginning of that number so they are first. I'm going to try to shake that thinking or that connection and try to use your thinking instead.

Hey. I'm going to ask a very weird and may seem like I'm joking question but I'm really not. I don't know what is meant by last digit of a number. That would mean there is a first digit. Is it right to assume that the last digit in 123567 is 1 and the first digit is 7?

My cat likes peach. He was begging for my baby's pureed peaches and he ate them right up.

That's exactly what I asked. Thanks so much leslie. I just thought it was possibly a dumb question but you reassured me.

Dumb question. After expanding (x+y)^3 in pretend world, is it universal to consider y^3 or x^3 the first term? Is there a universal definition for first term?

Thanks Ted. The calculator was super super close. I understand to expect that sometimes. It is interesting though what the algorithm is when something like this does happen.

Yep forgot to put some 1's (or 1's in the right place).

Should be [ 1 , 0 , 0 , 1 ; 0, 1 , 0 , 0 ; 0, 0 , 1 , 1] since 1^2+1=2 and 2^2+1=5 and 3^2+1=10 . Also thanks for responding.

Hi. Is it appropriate to ask what algorithm the ti-84 uses on mathstackexchange to calculate, say the row reduced echelon form of the matrix [1 , 1 , 1 , 2; 4 , 2 , 1 , 5 ; 9 , 3 , 1 , 10]. I was curious because the second row, last column is something super ridiculously close to 0 that should actually be 0. I'm just curious why it is super close and why the calculator doesn't show 0 there instead. I know it is a calculator and can mostly be trusted about alot of calculations.

When people talk about the tails on box plots, are they talking about just the whiskers or are they talking about anything after or before the median?

ok I guess I will put a picture...

Hmm... okay. I guess I will just copy and paste my comment into the answer spot. Thanks.

Am I crazy? math.stackexchange.com/questions/3191258/… Does his reply seem totally random, like he looked at a differentn response?

I did find it

you were extremely helpful

Thanks so much kevin

thanks kevin... i will try to find that :)

I'm trying to figure out why one of my comments were deleted. Where would be the best place to ask this?

but yeah no need for derivative

unless it asked for rate of change aka instantaneous rate of change at a particular value

oops (f(3/4)-f(0))/(3/4-0)

average rate of change for the function $f(x)=(4x+1)^{\frac{1}{2}}$ over the given interval would just be $\frac{f(\frac{3}{4})-f(0))}{\frac{3}{4}-0}$

You are probably right. I would rather them get this now then me reteach it to them in 9th grade or some other grade.

very small

Hi. I don't know if this is off topic for this room and if it's a stupid question like maybe you are already a moderator. But amWhy why don't you run for moderator? I'm serious. I know I'm not super active but I have seen you respond in several spots of the site. And you almost always convince me with your choice of words. They are always well thought out and very clear.

just a chat thing I think

So if I flag something on the mathematics page not the chat do you see that to @Catija ?

It has massive functions unknown to me

Yeah I'm still learning how this site works.

It probably isn't a comprehension thing but more of I disagree thing. :p

I do really mean the thanks and going out of your way to explain.

Thanks catija for answering my questions. Though I'm still totally lost and there is probably nothing you can say that will help me understand my comment being seen as useless and trashed. Sorry for not understanding.

but there comment stays as if it was more useful or something

That's a little sad... How can my comment be less helpful though than comments that are not actually useful at all? How is that weighed?

Still don't believe it should have been deleted due to not posting it as a answer

I guess it was more of an answer than a comment .

I don't understand why something meaningful to the conversation should be deleted

That was one of the suggestions :p

I should undelete..

I deleted it because I was advise to.

I followed the advice/suggestion.

I put a question there in feedback and it was downvoted and I was advise to do something else.

The feedback place?

Thanks in advance for a response.

I'm dumbfounded as to why my comment was considered useless to the topic

on math.stackexchange.com/questions/2564114/…

I had a question about a comment of my being deleted

hello

dumb question, but is this the math mod chat?
