Let $n$ be a positive integer. We denote the set $\{0,...,n-1\}$ by $\mathbb{Z}_n$.
We consider two integers $x, y$ to be the same if $x$ and $y$ differ by a multiple of $n$, and we write this as $x = y \pmod{n}$, and say that $x$ and $y$ are congruent modulo $n$. The $\mod{n}$ is

$a$ and $b$ are real numbers.
demonstrate the following equality.
$|ab|=|a||b|$
I have no idea, how to prove that.
I just know $|a+b|\leq|a|+|b|$ so i dont know how to start.

3rd Conversion Problem / Question
There are approx. 28.32 liters in a cubic foot. Go from there?.
I know I have to convert, but before I do so is the 12.5 x 15.5 x 8.0 the length that needs to be cubed to equal the volume?
$1\ ft = 0.3048\ m$ So to get the volume in $m^3$, you do this calulcation: $12.5 \cdot 15.5 \c... | 4 | [

What longitude might Lewis have calculated from this observation? That longitude would depend upon 1) the method he used for “clearing the lunar,” 2) how he interpolated the logarithms he needed to

Please i don't know how to even BEGIN this question.
A sequence defined as Sn(x) 1 + 2x + 3x^2.....nx^(n-1)
(I assume that the it is a geometric sequence and a is n and r is x? Am i correct?)

Gibbs Sampling
In this section, we describe Gibbs sampling, a general method for probabilistic inference. Gibbs sampling is well suited to coping with incomplete information and is often suggested for such
applications. However, generality comes at some computational cost, and for many applications including those inv... | 4 | [

Slope of a Line (Coordinate Geometry)
Definition: The slope of a line is a number that measures its "steepness", usually denoted by the letter m. It is the change in y for a unit change in x along the line.
