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. …

Arithmetic could roughly be described as working with the numbers we know within a particular system of numbers, and is often related in some way to working with things called integers …

I'm looking for clear mathematical rules on rounding a number to n n decimal places. Everything seems perfectly clear for positive numbers. Here is for example what I found on …

Jan 10, 2020 · Just to clarify: any finite set of real numbers can be viewed as part of an arithmetic progression,. My example gave an infinite set which is clearly not part of an arithmetic …

What do you mean by “a more mathematical approach (rather than using a defined floor/ceil function)”? I don't see how having predefined modulo is more mathematical than having …

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. …

Feb 19, 2014 · I have attached an image showing a Modulo 2 binary division. I can roughly understand the working below which is using XOR calculation but I am not sure how the …

10 How can I solve quadratic equations using modular arithmetic? E.g. 2x2 + 8x + 2 = 0 (mod 23) 2 x 2 + 8 x + 2 = 0 (mod 23) N.b. I have changed the figures from those in my homework …

Solve for (-1) (-1), and you get (-1) (-1)=1. So, we must have (-1) (-1)=1 if we accept basic rules of arithmetic: 0 is the additive identity, 1 is the multiplicative identity, -1 is the additive inverse of 1, …

Both the negative sign symbol and subtraction's minus symbol look the same, so how does anyone tell them apart?
