In hexadecimal, the number 4 is represented as 4. The hexadecimal system is used in computing for representing colors, memory addresses, and other data.
Mathematical Operations
Four is a versatile number that can be used in various mathematical operations. It is the only number that can be written in four different ways using the basic mathematical operations of addition, subtraction, multiplication, and division. For example, 2+2=4, 8-4=4, 2x2=4, and 16/4=4. Four is also a factor of several other numbers, including 8, 12, 16, and 20.
Ordinal Numbers
In English, the number 4 can be written in ordinal form as "fourth". This form is used to indicate the position of something in a sequence. For example, "The fourth book in the series" or "The fourth place winner of the race".

Fibonacci Sequence
The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding numbers. This sequence can be used to represent 4 by adding the second and third numbers in the series. Therefore, 4 is the sum of 1+3 or 2+2 in the Fibonacci sequence.
Chemical Element
The number 4 is also significant in chemistry. It is the atomic number of the element beryllium, which is a hard, lightweight metal that is used in alloys and nuclear reactors. Beryllium has four protons in its nucleus, which determines its atomic number.
Geometric Shapes
Four is a significant number in geometry, as it is the number of sides in a square. A square is a regular polygon with four equal sides and four right angles. Four is also the number of vertices in a tetrahedron, which is a three-dimensional shape with four triangular faces.
