MHB Solving 0x10 + 0xfe: What's the Answer?
Hint: if you use 16bit - 1) 0x10 + 0xfe = 0x10e 2) 0x20 + 0xfe = 0x11e And in 8 bit: 1) 0x10 + 0xfe = 0x0e 2) 0x20 + 0xfe = 0x1e So it is more about overflow than reset.- mathworker

MHB Probability of Winning a Game with Random Number 0-1/2
B is playing a game in which he has to choose a number A between 0 and 1/2 and his probability of winning if he choose A is $$A^2$$. I have encountered this at middle of some-other problem and couldn't make a move...- mathworker

MHB Johns Born Same Day: 24M Humans, 4 Letters
Prove that least two humans named John should have born on same day(means with same D.O.B) if world has only 24 million humans and their alphabet chart contain just 4 letter 'J','H','O' and 'N' and there can't be more than one million humans of same name and world started just 2739 years ago...- mathworker

MHB How Do We Prove That 'P' Doesn't Vary for Different Free Variables?
I am studying Introduction to linear Algebra by Gilbert Strang while calculating the particular solution P for $Ax=b$,he made the free variables $0$ to calculate the particular solution and said that P along with linear combinations of null space solutions make up the complete set. I understood...- mathworker

MHB What are the values of a, b, and c in the following equations?
In, $$\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=1+\frac{1}{abc}$$ L.H.S to be greater than one (a,b) should be (2,3) substituting them rest is linear equation $$\frac{1}{2}+\frac{1}{3}+\frac{1}{c}=1+\frac{1}{6c}$$ $$c=5$$- mathworker

MHB What are the values of a, b, and c in the following equations?
yeah I got it max value is not 1 $$its \frac{13}{12}$$ - - - Updated - - - But,I guess (2,3,5) is the only solution...(Smirk)- mathworker

MHB What are the values of a, b, and c in the following equations?
Since modulo is "zero" there is no remainder. $$\frac{(ab-1)(bc-1)(ca-1)}{abc}$$ is not a fraction $$abc-a-b-c+\frac{1}{a}+\frac{1}{b}+\frac{1}{c}-\frac{1}{abc}$$ is not a fraction So the little terms must sum it up to zero or 1 so, $$\frac{1}{a}+\frac{1}{b}+\frac{1}{c}-\frac{1}{abc}=0$$(let)...- mathworker

MHB Can the RMS-AM inequality prove the combinatorial coefficient inequality?
as $$C_0,C_1,C_2,...,C_n$$ are combinatorial coeffs of $$(1+x)^n$$. n is certainly an integer which is $$\geq 1 $$. the rest is obvious...:)- mathworker

MHB Can the RMS-AM inequality prove the combinatorial coefficient inequality?
use $$(2^n-1)*n\geq\frac{(2^n-1)}{n}$$ and then $$AM\geq GM$$- mathworker

MHB Evaluating definite integrals via substitution.
As you have not changed $$x$$ to $$u$$ you can't change limts from $$\int_0^1$$ to $$\int_1^2$$:rolleyes:- mathworker

MHB How many combinations of r natural numbers add up to n?
Thanks for the link,I have gone through it. But as far as I understood partition function doesn't give the number of partitions of specific cardinality.I mean if we want only the partitions that contains $$r$$ terms for example or can we define a restricted partition function that can do the...- mathworker

MHB Solve for r,t in the Polynomial $3x^3+rx^2+sx+t=0$ with a,b,c Prime
Re: find f and t It may not be an ellegent one i just gave it a shot$$ \begin{align*}c^2+2c+1&=4a^4\\c&=2a^4-b^2\end{align*}$$ I gave a try at a=2 so b is 5 and c is 7. And 7 is also the first prime to satisfy both equations even individually too. So r is -52 and t is -210- mathworker

MHB Have you ever been ragged at college?
As I am going to attend my university education by this weekend,one thing that I am thinking of for a while is ragging(or Hazing).Though there is anti ragging committee and zero tolerance policy I heard ragging(Hazing) is common.Have you ever experienced it?- mathworker
