a lot of that isn't even algebra  The questions I asked are all basic/pre algebra. What makes it algebra, is the process you have to follow in order to solve the problem, not the fact that there is basic addition and multiplication involved. |

(5+2)(5+2)= (25+10)(10+4)= (35)(14)= 490 ok, so it's multiply? all the others equal 490, the first one still makes 49. No? I like maths, it just doesn't like me |

I'm under the impression that algebra involves solving for a symbol/variable.
I would imagine that (35)(14) for instance, is just basic arithmetic, because it is only simple multiplication. |

well you do everything inside parenthesis first, then square roots, then multiply/divide, then add or subtract
if that's the order you are talking about |

(35)(10) is basic arithmatic, yes, but in this case (35)(10) was part of an entire other equation, and the solving of that equation is what makes it Algebra. Yes in Algebra you figure things out using different variables, but it is also the process in which you apply those variables. In the end, all mathematics breaks down to basic arithmatic. |

well what I'm saying is that your little FOIL problem is just basic math
 who else remembers FOIL? damn I feel nerdy now

I think I put the order of operations in the wrong order, oh well.
Well, actually I just shouldn't have mentioned parenthesis, they make it complicated exponents/roots multiply/divide add/subtract that's the order |

yeah, that's it
I haven't had a math class since I was 17

omg! I was able to get thru all except #3, and then the first question changed and I can't remember anymore than the simple equations. My brain is about to explode lol

I've forgotten most of the math in my life, but I used to be really good at it

I can still do prealgebra or basic algebra, but not much else

*phew!* everyone seems to have the same answers I did. That's because we all copied from you hahaha |

I am curious to see how many people can (assuming they are willing t do so) answer these next five questions. They are basic algebra equations that can be found in most if not all highschool algebra books. 1. (5+2) x (5+2) = 2. 2(5+2) x (5+2) = 3. 21B + 21A = -2B - 20A (SIMPLIFY DOWN) 4. A + B + C = 21 IF A IS EQUAL TO 7 AND B IS EQUAL TO 10, WHAT IS C? FOR THE LAST QUESTION, X=57 3X + 2X = 285 true or false Oooh. I was great at Math in school. Let's see :) 1. (5+2) x (5+2) = 7 x 7 = 49 2. 2(5+2) x (5+2) = 2(7) x 7 = 14 x 7 = 98 3. 21B + 21A = -2B - 20A 21B + 2B = -20A - 21A 23B = -41A God where did I get lost on this one?! I don't see where I can simplify [sobs] 4. A + B + C = 21 IF A IS EQUAL TO 7 AND B IS EQUAL TO 10, WHAT IS C? 7 + 10 + C = 21 C = 4 FOR THE LAST QUESTION, X=57 3X + 2X = 285 true or false 3(57) = 171 2(57) = 114 171 + 114 = 285 True |

1. (5+2) x (5+2) = 49
2. 2(5+2) x (5+2) = 98 3. 21B + 21A = -2B - 20A (SIMPLIFY DOWN) 19B + A 4. A + B + C = 21 IF A IS EQUAL TO 7 AND B IS EQUAL TO 10, WHAT IS C? C=4 FOR THE LAST QUESTION, X=57 3X + 2X = 285 true or false it is true |
