Parentheses usually refer to symbols used to indicate notes in an article, with common types including round brackets (), square brackets [], curly brackets {}, and so on.
Number base calculations mainly involve converting between different bases. The core method is to convert other bases to decimal using 'expand and add by place value,' and convert decimal to other bases using 'divide by the base and take the remainder' or 'multiply by the base and take the integer part.' Binary, octal, and hexadecimal can be quickly converted using the grouping method.
Gottfried Wilhelm Leibniz (1646-1716) was one of the rare all-round geniuses in German history, often called the 'Aristotle of the 17th century.' He's most famous for independently inventing calculus, designing binary algorithms and early computers, and making a deep impact on philosophy and logic.
Longitude refers to the angle between the plane of the meridian passing through a point on the Earth's surface and the plane of the prime meridian, used to indicate the geographical location east or west on Earth. It ranges from 0° to 180° (east or west longitude). In geography, longitude usually refers to the horizontal coordinate in a spherical coordinate system, specifically the degree to which a location on Earth is east or west of a line called the prime meridian.
