Math

I wouldn't call myself quite a math freak… but I do enjoy it, enough that I occasionally like to think up problems and then find the answer using algebra. :)

To start off conversation, did you know that if there are 23 people in a room, there is roughly a 50% chance of any two of them sharing a birthday? :D

Why, oh why, would you bring such a horrible topic to this lovely place???! xP jk

I've heard that too, but… that just seems… impossible… xP

I know; I don't understand it either. :) Infinity is impossible for us to comprehend. And just think about how God is _infinitely_ good! Isn't that amazing?!

Indeed!! :D Blows the mind to try to imagine it. :D

I've heard of that before… it's really neat!

ummm…… xP xP Cause I enjoy it?

It's not horrible just because you don't like it. That's just your opinion. =)

Do you all prefer Algebra or Geometry? (For those of you who like math.)

Algebra, certainly. Geometry involves too much… I don't know, context. You have to keep a lot of things in mind all at once to succeed.

Yeah, I know that, I don't really really not like it, but it just isn't enjoyable for me. I was joking. :D

^^ Exactly the same here:)

Probably gemoetry…but I haven't done Algebra II yet, so maybe I'll end up liking Algebra better after all. ;) However, since I'm not as much of a math person, I enjoy the logic and graph stuff that geometry has— it's got more than just the typical numbers and equations.

I'm definitely not as much a numbers person (math and science) as I am a words person (grammar, writing, literature). History and geography are kind of in the middle, because they've got words and numbers (and visuals!). But I try to enjoy every school subject, and usually I do. =)

Does anyone know any good logic puzzles, or like trying to solve them? My day's coworker finds them on the Internet and tells my dad, and then my dad tells us ;)

I definitely like Geometry better of the two. Though, I prefer Trig over them all. :) When I took my ACT, Trig is what I scored the best in. I am definitely someone who likes things to work logically in my mind, and prefer Chem and Trig way over Writing or Reading. Though, I do like reading a good books. :)

Of all the math subjects I have had, I liked Algebra 2 best! :)

That. was. the. worst. school. I. have. ever. ever. ever. taken.

I would like it now, because I've come to learn to like things like that (like, math and science), but back then, I nearly died in that book. Besides, spending 3 hours on a 30 minute lesson, is not fun.

Actually, that's what I thought of Algebra 1! :P I guess my brain did a lot of growing up between Algebra 1 and Algebra 2. :)

"…and then Satan said, 'put the alphabet in math' "

I think Algebra is great! :D

"...and then Satan said, 'put the alphabet in math' "

Yep!!! I like all math up to Algebra, but I have done a little bit of Geometry, and that I like, but I don't get to do it until I am done with Algebra. :(

Algebra, hands down. Geometry was fun, but it takes a really long while to develop all those proofs. xP

Several days ago I figured out a formula to find the sum of any number of consecutive integers… :) Take the square of the largest number, subtract the square of the smallest number, add the sum of both, and divide it all by 2. xD Or for those who prefer formulae in algebraic form, (L ^2^ - S ^2^ + L + S)/2.

I think Algebra is great! :D

Me too! I'm on my way through Algebra 1, cause I made it 1/2 way through the first time and had to start over… but I LOVE it!!! :D

Ditto! :-)

What?!?!? wonders how anyone could possibly like algebra

What?!?!? *wonders how anyone could possibly like algebra*

wonders how anyone could hate algebra

wonders how anyone could like being totally confused

So I have this math problem that I don't fully understand. I'd appreciate if anyone could help explain it.

Given any numbers a and b, a :) b is defined as a+ab+b. For example, 2 :) 3 is 2+2x3+3=11. Operation :) is both commutative and associative (You can prove that if you want…).

a) What number is the identity of :) ? In others words, what is the number I such that x :) I = x for all values of x?

b) What number is the inverse of 1 with respect to :) ? That is, what number goes in the blank to solve __ :) 1= I, where I is the number you found in part a)?

And can someone help me understand why (a+1)(a+1) = a(a+1) 1(a+1) ?

Those look like tough math questions. I tried doing them on paper and this is what I cam up with.

a) The identity that I came up with was the number zero. Because if X+X(0)+0=X, then no matter what you put as X, The answer comes as X. You can try it using a calculator, and it should come out right.

b) The inverse of 1 that I got was (-1/2). That is because if X + X(1) + 1=0, then you use algebra to get it down to the variable on one side, and a number on the other side. Taking the that equation, I multiplied the 1 with the X in the middle of the equation and got X + X + 1=0. Then you add the Xs on one side and minus the 1 on both sides, turning the equation into 2X= (-1). If you then divide 2 on both sides you get X=(-1/2) or X=(-.5) which are the same thing.

c) As for your other question on (a+b)(a+b)=a(a+b)1(a+b), who told you those were equal? Because I tried solving the equation and they do not work out as being equal. They are both the same except that the right side just added an "a" to the equation, increasing the right side by multiplying it by "a."

I hope that I got your meaning in the questions and answered them correctly. Hope it helps.

Because if X+X(0)+0=X, then no matter what you put as X, The answer comes as X. You can try it using a calculator, and it should come out right. That's right :) My book came up with a slightly different solution. x :) _I_ = x + x_I_ + _I_ For the right-hand side to always equal x, x_I_ + _I_ must equal 0. Factor the _I_ gives (x+1)_I_, which is 0 for all x if _I_ = 0. But your solution is more intuitive :) b) The inverse of 1 that I got was (-1/2). That is because if X + X(1) + 1=0, then you use algebra to get it down to the variable on one side, and a number on the other side.

Because I tried solving the equation and they do not work out as being equal. They are both the same except that the right side just added an "a" to the equation, increasing the right side by multiplying it by "a." Whoops! I wrote it wrong! It's supposed to be (a+1)(a+1)=a(a+1)+ 1 (a+1). It was a part of a proof of the formula (a+1)^2 = a^2 + 2a + 1. (a+1)^2 = (a+1)(a+1) = a(a+1) + 1(a+1) = a^2 + a + a + 1 = a^2 + 2a + 1. I _think_ I figured it out. It basically uses the diagram of a grid. Imagine a = 2. So the grid would be 3x3 (2+1 = 3). If you make _a_, 2, and go through the formula using the grid it works; it's basically another way of counting the squares. 2(2+1) would be the 3x2 column on the left. 1(2+1) would be the 2x1 column on the right. Can you explain how the algebra works? I don't get that. EDIT: It's just the distributive property. The parenthesis confused me :P I hope that I got your meaning in the questions and answered them correctly. Hope it helps.

Thanks!
