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 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,

For commutative arithmetic, why do we have 'asymmetrical' nomenclature like 'multiplier x multiplicand' and 'augend + addend'? Hot Network Questions What is a plausible reason for the extra hardware/cost for the Sol-PC "phantom" ROM?

If you tell me $16\cdot 3$ is less than 45, I'm going to be suspicious, because I know $15\cdot 3=45$, and so $16\cdot 3$ must be greater than 45. This is a very simple example of much more powerful theme: don't think you've finished an arithmetic problem when you've gotten a final result. You should check that result against your intuition ...

Feb 16, 2018 · 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

Apr 23, 2019 · 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.

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.
