2. Field (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Field_(mathematics)

   Dropping instead commutativity of multiplication leads to the concept of a division ring or skew field; [g] sometimes associativity is weakened as well. The only division rings that are finite-dimensional R-vector spaces are R itself, C (which is a field), and the quaternions H (in which multiplication is non

3. Multiplication - Wikipedia

   en.wikipedia.org/wiki/Multiplication

   Multiplication (often denoted by the cross symbol, ×, by the mid-line dot operator, ·, by juxtaposition, or, on computers, by an asterisk, *) is one of the four elementary mathematical operations of arithmetic, with the other ones being addition, subtraction, and division. The result of a multiplication operation is called a product.

4. Elementary arithmetic - Wikipedia

   en.wikipedia.org/wiki/Elementary_arithmetic

   The numbers being multiplied are multiplicands, multipliers, or factors. Multiplication can be expressed as "five times three equals fifteen," "five times three is fifteen," or "fifteen is the product of five and three." Multiplication is represented using the multiplication sign (×), the asterisk (*), parentheses (), or a dot (⋅).

5. Distributive property - Wikipedia

   en.wikipedia.org/wiki/Distributive_property

   In approximate arithmetic, such as floating-point arithmetic, the distributive property of multiplication (and division) over addition may fail because of the limitations of arithmetic precision. For example, the identity 1 / 3 + 1 / 3 + 1 / 3 = ( 1 + 1 + 1 ) / 3 {\displaystyle 1/3+1/3+1/3=(1+1+1)/3} fails in decimal arithmetic , regardless of ...

6. Operation (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Operation_(mathematics)

   Binary operations, on the other hand, take two values, and include addition, subtraction, multiplication, division, and exponentiation. [4] Operations can involve mathematical objects other than numbers. The logical values true and false can be combined using logic operations, such as and, or, and not. Vectors can be added and subtracted. [5]

7. Arithmetic - Wikipedia

   en.wikipedia.org/wiki/Arithmetic

   The main arithmetic operations are addition, subtraction, multiplication, and division. Arithmetic is an elementary branch of mathematics that studies numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms.

8. Chapter (books) - Wikipedia

   en.wikipedia.org/wiki/Chapter_(books)

   Many ancient books had neither word divisions nor chapter divisions. [1] In ancient Greek texts, some manuscripts began to add summaries and make them into tables of contents with numbers, but the titles did not appear in the text, only their numbers. Some time in the fifth century CE, the practice of dividing books into chapters began. [1]

9. Commutative property - Wikipedia

   en.wikipedia.org/wiki/Commutative_property

   The Egyptians used the commutative property of multiplication to simplify computing products. [7] [8] Euclid is known to have assumed the commutative property of multiplication in his book Elements. [9] Formal uses of the commutative property arose in the late 18th and early 19th centuries, when mathematicians began to work on a theory of ...
