    Memory Chip Poll: Should We Have a Memory Chip in Our Head?

    I say no.Bcoz our brain is more effective than memory chip.We r using only less than 5% brain of our toatal brain.So we must learn to use our full brain.

    High School How to Solve Equations with Positive Integer Solutions?

    I need to solve this kind of equqtions x^2-y^2+ax-by = c a,b,c are know.I want to find out x & y. note: a,b & c are positive integers I need only positive x & y pairs in integers.

    Undergrad Can (x+y) + xy = C Be Solved for Even Numbers?

    I have an equation of type (x+y) + xy = C C is known & both x,y,c are even numbers.Whether is it possible to find x & y from this equation? How many posiible x & y in that equation? Ex: (x+y) + xy = 6496

    Undergrad Can You Solve ax+ay-xy=c for x and y Deterministically?

    how do u derive the equation x = a + \frac{c - a^2}{a - y}

    Undergrad Can You Solve ax+ay-xy=c for x and y Deterministically?

    In this type of equation 1.x and y are the possitve even no integers between (a-1) and (a-1)/2. 2.a is always a odd no. 3.c is always a even no. So Ramsey We can't use your method.Thanks a lot for your reply

    Euler’s Phi-function In the eighteenth century, the mathematician Leonhard Euler (pronounced “Oiler”) described f(n) as the number of numbers less than n that are relatively prime to n. The character f is the Greek letter “phi”. This is known as Euler’s phi-function. Remember that relatively...
