Apr 21, 2015 · Is there a notation for addition form of factorial? $$5! = 5\times4\times3\times2\times1$$ That's pretty obvious.

I'm trying to mentally summarize the names of the operands for basic operations. I've got this so far: Addition: Augend + Addend = Sum. Subtraction: Minuend - Subtrahend = Difference. …

Aug 1, 2017 · The same principle applies to more than two segments: given a series of sub-trips at different speeds, if each sub-trip covers the same distance, then the average speed is the …

Of these, I'm personally rather fond of "round $\frac 1 2$ to nearest even number", also known as "bankers' rounding". It's also the default rounding rule for IEEE 754 floating-point arithmetic as …

So a little arithmetic will suffice to solve this simple problem: We begin with the husband, who gets 25%. The son gets two shares and three daughters each get one share of the remaining 75%. …

Nov 26, 2014 · An arithmetic sequence is characterised by the fact that every term is equal to the term before plus some fixed constant, called the difference of the sequence. For instance, $$ …

Jan 10, 2020 · Thank you @Henry.. I finally see it. So basically arithmetic is having a support for the random variable that can be say, modeled, as some arithmetic progression or series. And …

Nov 9, 2015 · Update: I had an idea to minimize the number of needed arithmetic rules via generalizing the concept of asymptotic notations. I describe this idea in the MO thread …

How does someone mathematically round a number to its nearest integer? For example 1.2 would round down to 1 and 1.7 would round up to 2

How can I solve quadratic equations using modular arithmetic? E.g. $$2x^2 + 8x + 2 = 0 \pmod{23}$$ N.b. I have changed the figures from those in my homework question because I …
