1) Natural Numbers are numbers that you count.  They are 1,2,3,4,5,6,7 and so on and so forth starting with one.\n2) Whole numbers are numbers that have no decimals.  They are like -1,0,1,2,3,4,5 and so on towards positive and negative infinty.\n3) Integers are the same as whole numbers.\n4) Rational numbers are numbers that can be expressed in a fraction.  Like 21/7ths.\n5) Irrational numbers are numbers that cannot be expressed in a fraction.  Like the square root of 6.5.\n6) Decimals are pieces of a number like .12 dogs or .75 cups of water.\n7) Repeating decimals are decimals the repeat forever.  Such as 1/3 is .3333333 repeating.\n8)  Terminating decimals do not repeat forever.\n9) Solution sets are sets that solve a problem.\n10) Finite sets are sets that have a final answer.\n11) Infinite sets go on forever.\n12) Empty or null set is a problem with no answer.  It looks like a circle with a line through it.\n13) Domain is what x values the function passes through.\n14) An open sentence is a sentence the doesn't end.\n15) An equation is two things connected by a equals sign.  Such as 4x+y=13-7a\n16) Inequalites are two things connected by a greater then or less then sign.  15>2.\n17) Addition is adding numbers 4+5=9.\n18) Multiplication is timesing numbers like 4x5=20.\n19) Polynomials are numbers with more then one term.  Like 4x+5+6y

The world nows that the "numerator" is the number on top of a fractional expression, and that "denomanator" is not a word, but that "denominator" is the number on the bottom of a fractional expression.  I congratulate you on already "nowing" this, since this means your math skills greatly outscale your English language skills! LOL

generally, you combine like terms and then subtract the same thing from both sides and/or divide both sides by the same thing.  but that may b 2 vague to help much.  i need a specific question.

The best place to go for math help online that i found was \nhttp://www.math.com\nI hope its useful to you.  I know people on here can tell you the answers, but if you have a test to take, and want to really learn it, go there.

I posted these sources earlier to someone else who was looking for math help.\n\nGood Luck!!

1.  (0,y)\n2.  (x,x) or (y,,y)\n3.  they are three whole numbers that will satisfy the pythagorean equation, a^2+b^2=c^2. ("^2" means raising the number to 2).  an example would be 3,4,5.\n4. 12\n\nFOrmulas\n\n1.volume:sphere= (4/3)*pi*r*r*r\n\ncone = (1/3)*pi*r*r*h\n\n2.circumference is 2*pi*r

Oh, how dismal it was! They did not have a "decimal" or fraction system, but instead used words. Go here for more information:\n\nhttp://mathforum.org/dr.math/faq/faq.roman.html#calc

My honest suggestion to you is that you re-post this question in the Mathematics category.\n\nBut as you are in Words and Wordplay, I must commend you on very nice punctuation!

this is probably not a perfect answer but this site may give you some clues.\n\nhttp://www.gomath.com/Questions/question.php?question=4751\n\naltrnatively type 'prove v*v = 2gr*r/s+v0*v0-2gr' into a search engine and see what comes up.

it is a monomial\n\n\nMonomial is an algebraic expression consisting of a single term.\n\nBinomial is a polynomial with two terms. Example:(2x+3)\n\nTrinomial is a polynomial consisting of 3 terms.

Google the word algebra help.  Purple math is great, but there are other sites also.  I am sorry I do not have the names at the moment.

I think this means:\n\n(t^2 - 2t - 15)/(t-5) * (t+5)/(t+3)\n\nIf that's right, then\n\n(t^2 - 2t - 15)/(t-5) * (t+5)/(t+3) = (t-5)(t+3)/(t-5) * (t+5)/(t+3)\n= t+5

I'll give you some hints, but I won't answer them for you:\n1) The difference between terms (2, 4, 8, ...)\n2) 1, 4, 9, 16... and 1, 8, 27, 64... \n3) 1!, 2!, 3!...\n4) perhaps look at every other term...\n5) n! and n^2\n6) The difference between terms (1, 3, 6, 10, ... , 1+2+3+..+n)\n7) Look at these as base 7 number (12 base 7 = 9, 22 base 7 = 16, etc.)

Wait a minute everybody!\nthose vertical lines,( lyl ) could mean absolute value!!\nHelloooo?\nso the answerSSS could be 9 and -9\nsheesh!

by any chance is this a question from your maths homework? lol :D\n\nI cant work it out myself because to put it simple, im crap at maths.

Crap!\n\nSomething to do with Pi.  When my friend was in college she used to say the first one.\n\nETA:  They are both frases said to remember the numerics of Pi.

The ∞ mean infinity.  So, it goes from -infinity to 8, not including 8 itself.  And the other one goes from 5 to infinity, including 5.\n\nThe [ ] means that you include that end point, whereas ( ) means you don't include that point.
