3. 2 + 8 = 10

Thats what I get....

Why do you use wierd seperators?

( - (-2) ) + 4( (-1)-3)
minus minus 2 equals 2, + 4(-1 - 3), takes it out the brackets, so -4 - 3 which equals -7, I get -5.

EASY.
But let me tell you, SHEESH, this is too easy.

Im in 7th grade doing algebra right now and its pretty easy just simplifying eqautions like this:
4x+3-51/2(2/11-2x)-1=

4x+3-11/2(2/11-2x)-1=

4x+3-1+11x-1=

15x+1 Its pretty easy since this is all just review from last year in Pre algebra

-1 - 3 is the same as -1 + (-3) so that would be |-4|

The answer is 18.

Well we're doing Postulates and Theorems and suchwhat.

This. Geometry CP in 9th grade for me right now.

I don't really know WHAT we're learning because for the whole month all we've been having is stuff from last year. *faceppalm*
7th Grade. But I don't really know what my book is. tongue

7th grade.

Shadowsonics · 2011-09-27 17:45:40

Algebra I Honors.

Wickimen · 2011-09-27 19:16:10

7th grade "Pre-Algebra Enriched"
The book just says Pre-Algebra
Meh I dislike math

It's not hard once you get used to it. ;D

Oh, someone else in calculus? Cool! We're on derivatives in my class. Speaking of which,
I should probably be studying for my quiz on it tomorrow. neutral

i'm in ninth grade and i'm doing geometry
i hate math

maxskywalker · 2011-09-27 20:59:50

Um, I'm doing the commutative and distributive properties and stuff... whole lotta review in the beginning of the year.

Which definition of continuity are you exploring? Theta epsilon? Graphical? smile

I am a freshman and am taking accelerated precalculus -> calculus this year.

imnotbob · 2011-09-27 21:04:37

I'm actually really enjoying math big_smile

Lol, you don't need to convert it to the positive amount. Any negative/positive number multiplied by positive numbers is positive. tongue

MoreGamesNow · 2011-09-27 21:11:58

From what I hear, 50% of this year is review of Algebra II, and the other 50% is covered again in Calculus. I haven't learned anything (yet). Why does it take 2.5 years to cover algebra??

That isn't true :S If you multiply a negative by a positive the quantity is negative.

Anyway, the error you are making is in the second step. -1 - 3 = -4 and |-4| = 4 and 4 * 4 = 16. This means the final answer is 18.

imnotbob · 2011-09-27 21:13:17

Right now we're doing inequalities. We're going to start harder stuff soon, though.

Which is easy for me because i was the 2nd kid in 3rd grade

0_0 I was forced to learn multiplication in 2nd.

I'm way ahead of the 8th grade standards. Geometry/Beg. Trigonometry and AP Physics.
