- Real life example to explain the Difference between Algebra and Arithmetic
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% The son gets two shares and three daughters each get one share of the remaining 75%
- Arithmetic mean vs Harmonic mean - Mathematics Stack Exchange
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
- arithmetic - What are the formal names of operands and results for . . .
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 Multiplicati
- arithmetic - Rules for rounding (positive and negative numbers . . .
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 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
- Finding modular of a fraction - Mathematics Stack Exchange
In the context of cryptography, I need to find the private key of a message and I need to use modular arithmetic I understand how modular arithmetic using a clock with whole numbers But I get really stuck when I get to fractions, for example: 1 3 mod 8 How do I find a modular of a fraction? Is there a method for finding this? Thanks in advance!
