Here’s a good reason to pay attention in math class. Nature Communications has published a paper from Ottawa researchers today, outlining how advanced mathematical modelling can be used in the fight against cancer.
The technique predicts how different treatments and genetic modifications might...
In the future, if you want to improve your ability to manipulate numbers in your head, you might just plug yourself in. So say researchers who reported in the Cell Press journal Current Biology on studies of a harmless form of brain stimulation applied to an area known to be important for math...
Tonight's Glee finale left us with one burning question: Was that really a final goodbye to Heather Morris? We aren't experts in quantum mechanics like MIT-bound Brittany, but we...
A concession stand charges $1.50 per soda and $2.50 per popcorn box. Write an expression for the amount of money you would need to buy x sodas and y popcorn boxes.

Thanks guys! :)
My school uses this grading system: homework counts as 15% of your overall grade, quizzes count as 40%, and tests count as 45%. Anyways, I took a quiz on integers and I'm pretty sure I f*cked it up. there were about 4-5 questions out of the 25 questions that had integer equations and i did them...
Im searching for a website with math riddles and puzzles.
I have found some sites but my point is that without ranking (points for each riddle you solve) it's no fun.
anyone knows this kind of site?
Computer Technologies? I'm not sure what jobs i can go on using these subjects and i need help. also I am good at Math and do the harder math at my school. im particulary good at Business Computer Technologies and Modern History and okay at english. im pretty good at health and Geography as well.

This is level algebra 1. It is chapter 10 and I have a quiz tomorrow and the instructions are: " Simplify each rational expression if possible. Identify any excluded values.
The original problem is 2x/ x^2-3x
i need help finding the excluded value. I already simplified it. I look in my...
I know all about the red equality sign and what it symbolizes, but now I've been seeing multiplication signs and even pi? What exactly is up with that? Are they just mimicking as a joke or is there something else I'm missing?
Ok I took two math quizzes and I studied and then I got a 55 and a 40. Ideas was really sad because I haven't failed any math test or quiz for the year but I have to get them signed how do I tell it to my parents
'The following puzzle requires you to sub one digit for A, and one digit for B. (This is not algebra). the digits are between 1 and 9. Neither A nor B will be zero.
AA x BA / A -15 = BAB
i need to know what BAB is. this is not homework, so please just answer :) thanks
yes i think BAB will be...
If I gave you 12 toothpicks, each 1 unit long, could you use them all to make a polygon with an area of 4 square units? Show your work please.
I've tried everything and I can't come up with anything :C
@AskJoe;; I asked my teacher that but he said it didn't count because it's 4 different polygons
base and exponent forbeach power
1. find the area of a square with a side of 6m. (hint area = s2)
2. Write an expression for 4 as a factor 5 times
this is for a practice test and i have nooo idea what do do
What follows is a proof that 1 = 2. Since we know that 1 does NOT equal 2, there is obviously an error in the proof. Your job is to identify it. It requires a year of high-school algebra, so anyone who has at least learned to factor should be able to give it a try.
If you've heard it before...
