2015年4月21日 · Is there a notation for addition form of factorial? $$5! = 5\times4\times3\times2\times1$$ That's pretty obvious.

2017年8月1日 · 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 harmonic mean of all the sub-trip speeds; and if each sub-trip takes the same amount of time, then the average speed is the arithmetic mean of all the sub-trip speeds.

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 used by most modern computers. According to that rule,

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. Multiplicat...

The term arithmetic underflow (or "floating point underflow", or just "underflow") is a condition in a computer program where the result of a calculation is a number of smaller absolute value than the computer can actually store in memory.

2018年2月16日 · I was looking around on the internet until I stumbled upon this equation. $$111111111\\times111111111 = 12345678987654321$$ How does this actually work? It is quite amazing how the number ascend and

2019年4月23日 · Now, this got me thinking about basic arithmetic and how to prove each operation, and I created a mental inconsistency between multiplication and division. Multiplication As this is an important part of the thought process that lead me down this mental rabbit hole, I am including the elementary explanation of multiplication.

2013年5月20日 · Many years ago, I noticed that $987654321/123456789 = 8.0000000729\\ldots$. I sent it in to Martin Gardner at Scientific American and he published it in his column!!! My life has gone downhill si...

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
