Math Tutoring discussion

i don't live in the us so i don't really know the levels (like algebra i, pre-calc, etc) - could anyone explain it? sorry !!

i would but idk either-

I understand that this is a math tutoring group but is anyone good at Physical Science Honors?

Hi!!

So after you take 8th grade math or the last math class in middle school then you're going to go onto Algebra 1 and then Geometry,

@fatima, tysmm !! so algebra 1 is like the start of the gcse course?

umm...no.

I just typed the US academic stuff.

I think you can look on the GCSE website for more detailed information.

Okay, how is 7÷0, 0. Because, if you have 7 things and you dont share them with anyone, dont you STILL HAVE 7!

.....am I subtracting?

No. I think in the math universe whenever you divide by zero it's so powerful that it takes the spot of whatever number you divide 0 by.

anything divided by 0 is undefined…. right?

wait... my BRAINS BREAKING

YEAH ITS UNDEFINED I JUST DOUBLE CHECKED- it doesnt have an agreed upon answer

yeah so basically how I understand it is imagine if you have 8 apples and you are giving out it in piles of 4 apples. 2 people would get a pile of apples. Now imagine it as if you have 8 apples and each person gets 0 apples, then how many people can get 0 apples. It just doesn't really work.
edited so its simpler lol

say for example you have 5 cookies and you have to share them with 0 people. dividing is basically sorting things into equal groups until there is nothing left, however if you give things to 0 people, you would still have 5 meaning there are more cookies to be grouped. this goes on for eternity which is why we say anything divided by 0 is undefined.
i hope this makes sense!!

Integrated calc and college algebra about to be so miserable 😩

Dividing by/from zero is undefined since there is no integer value besides zero to divide itself into/divide number in question by. 0 is a midpoint between the positive and negative integers and has only the value of 0, whereas something like 15 has many values that can be divided into smaller/larger parts. I.e 15 can be divided into three units of the integer 5, or two units of the integer -5 and one 5. Zero has no integer value besides itself, and also has no positive or negative value to change the value of the dividend. so if you were to try to divide by it you would have to divide infinitely, and if you were to divide from it you would have no values to take away from zero besides zero, in which case you’re left with zero.

Also to clarify confusion around say 15 divided into zero parts is 15, you can think about 15/1. You are taking apart 15 into 1 part, in which case you are left with 15. So 15/0 is taking 15 into zero parts, which you can get closer to the more you increase/decrease the integer value of the divisor, but don’t quite reach. However dividing by 0 one time doesn’t split 15 quite close enough to zero parts, so say you do it again. You then have to repeat this process infinitely, since you can’t achieve turning 15 into 0 integer values with an integer that has no value in of itself. For the same reason that you can add or subtract 0 to any real number and it will stay the same.

Oops that was kinda a bunch of paragraphs well hope that helped

Imma go back to being depressed now

hiii does anyone understand this?? im not rly sure of the topic:

a man walks at the rate of 88 paces to the minute. If the average length of his pace is 0.875m, find the time he takes to walk 2.31km

no but PERRY THE PLATYPUS OMGOSH MY GOATTTTT

Okay so i guess it works like this:

88 paces every minute, and each pace is 0.875 meters. If we combine those two, we can figure out how much meters he walks every minute. So:

88 x 0,875 =77 meters every minute.

77 meters is 0,077 km. (77:1000=0,077)

2,31 km is the total amount he walks. If we divide that through 0,077, we can figure out how many minutes he walked.

2,31 : 0,077 = 30 minutes


So the answer is 30 minutes! Hope this helped!!

so, the math courses in the US are weird as hell, but where i live, you take your grade math course unless you do honors, then you do the grade ahead of you - 6th does 7th, 7th does 8th, etc.
once you get to 8th grade, you have the choice between on level, honors, and algebra 1.
if you do algebra 1 in 8th and pass the final, you have that credit when you go into high school.
once in high school (assuming you have the algebra 1 credit), you can take either; geometry or algebra 2 (order doesn't matter) or you can double stack the classes and take both in one year.
at my high school, you only need 3 math credits to graduate (on the normal pathway) so if you double stack them freshman year, you can be done with math in high school by the end of freshman year (9th grade)
if you decide to take more math courses after you finish your 3 required, you can take pre calc, then calc AB, then calc BC - but i think you can only take BC if you double stack freshman year.
then there's this whole thing about pathways and pre-requisite courses - im not going into all that cause ill get comment limited if i try.

hope this helps <3

so basically in maths we’re doing like primes and square roots and that and like surds but the thing is i don’t really get it i mean i can do it sometimes in class but then i get confused with all of the steps so can someone please explain it to me
thanks🙃

oh my gosh okay
thanks haha <3

i go to a private school and this is mine:
7th (age 12-13 )- pre-algebra
8th (age 13-14 )- algebra 1
9th (age 14-15 )- algebra 2
10th (age 15-16 )- geometry
11th (age 16- 17)- algebra 3 (also called trigonometry)
12th (age 17-18 )- pick either calculus or consumer math

of course. But its different everywhere, this is just where I live - i know that in another state they do something called IM (integrated math) and then a number for the level - the us is so confusing

For math levels it completely depends on where you go.
Most freshmen (first years) start at either algebra 1, geometry or algebra 2.
The pathway goes (at my school):
Pre-Algebra->Algebra 1->Geometry->Algebra 2 (can take regular or honors then depending which you take you have two options)
Honors algebra 2->AP precalculus (feeds to BC)->BC calculus->Multivariable calculus
Regular algebra 2->AP Precalculus (feeds to AB)->AB calculus (but some choose to take AP statistics instead)

help I live in the UK and I do not understand what anyone is on abt lol

I'm pretty sure 8th grade is Year 9?

I go to a grammar school, basically all we do is just expand on things every year? So is that Algebra I, Algebra II etc?
