The main circuit board everything else connects to. Think of it as the backbone of your system.
The display screen. Comes in different sizes, resolutions, and panel types like LCD, LED, OLED.
Lets you precisely point at and interact with things on the screen. Gaming mice are a whole rabbit hole!
Useful for calls, voice commands, recording, etc. Laptop mics can be pretty hit or miss.
A lightweight markup language for formatting plain text. Used all over the web, including in this article!
Matroska Video. A versatile multimedia container that can hold video, audio, subtitles, and metadata.
Converts signals between analog (like cable or phone lines) and digital (like Ethernet). The bridge between your home network and the internet.
Catch-all term for malicious software like viruses, spyware, and ransomware. Only download from trusted sources.
In math, multiples describe the divisibility relationship between integers. If a divided by b equals c, and a, b, and c are all non-zero integers, then a is a multiple of b and c, while b and c are factors of a. It's like a rectangle with an area of 42—if the length and width are natural numbers, 42 is a multiple of both the length and the width.
Measurement usually refers to using instruments to determine specific values for things like space, time, temperature, speed, and so on. It can also mean checking or gauging various conditions like distance, depth, or height. For example, carefully measuring wall dimensions before buying furniture, or an engineer performing precise checks on a building, are all considered measurement.
Multiplication is a shortcut for adding the same number repeatedly. The result is called the product, and the symbol is '×'.
The multiplication table usually refers to the 9x9 multiplication table, which goes from 'one times one equals one' to 'nine times nine equals eighty-one.' It's a basic tool for doing math calculations. It uses the rules of the decimal system to simplify complex multiplication into easy-to-remember rhymes.
A map is a representation of the Earth's surface on a flat plane, scaled down using symbols according to mathematical rules. It's not just a simple photo, but a geographic model that's been filtered and summarized.
The metric system, also known as the meter system, is an internationally used measurement system based on decimal units and is also the foundation of the modern International System of Units (SI).
Measuring possibility (that is, probability) is a core concept in math, statistics, and decision science, mainly using probability theory to turn uncertainty into a number between 0 and 1.
The nine-nine table is what we usually call the nine-nine multiplication table. You memorize it from 'one times one equals one' to 'nine times nine equals eighty-one,' and it's the most basic tool for learning multiplication and division in math.
Matrix multiplication is the operation of creating a new matrix from two matrices according to certain rules. The key requirement is that the number of columns in the left matrix must equal the number of rows in the right matrix; otherwise, you can't calculate it. When calculating, the resulting matrix has the same number of rows as the left matrix and the same number of columns as the right matrix, and each element is obtained by multiplying and then adding the corresponding numbers from the row of the left matrix and the column of the right matrix.
Matrix subtraction requires the two matrices to have exactly the same number of rows and columns. When calculating, you subtract the numbers in corresponding positions one by one to get a new matrix with the same dimensions.
Minkowski space is a spacetime in special relativity that consists of one time dimension and three spatial dimensions. It was first described by the Russian-German mathematician H. Minkowski (1864–1909).
August Ferdinand Möbius (November 17, 1790 – September 26, 1868) was a German mathematician and astronomer, born in Schulpforta, Saxony.
The Möbius strip is a magical paper loop with only one surface and one edge, discovered by the German mathematician Möbius in 1858. You just twist a regular strip of paper half a turn and stick the ends together, and then an ant can walk across the entire surface without ever flipping over.
The average is just adding up a set of data and then dividing by the number of items, used to represent the general level of that set of data. It's the most commonly used statistical indicator, for example, calculating average grades or average salary uses it, but be careful—if the data has especially large or small numbers, the average can get skewed.
(Microorganisms) are a general term for lower organisms that are tiny in size, simple in structure, and usually need a microscope to be observed.
Medical care refers to the overall set of measures and services taken to prevent, diagnose, and treat diseases, as well as promote health. It's not just about curing illness—it also includes health maintenance and rehabilitation.
