   are solved using cross-multiplication, since the missing b term is implicitly equal to 1: a 1 = x d . {\displaystyle {\frac {a}{1}}={\frac {x}{d}}.} Any equation containing fractions or rational expressions can be simplified by multiplying both sides by the least common denominator .

4. Vector algebra relations - Wikipedia

   en.wikipedia.org/wiki/Vector_algebra_relations

   The following are important identities in vector algebra.Identities that only involve the magnitude of a vector ‖ ‖ and the dot product (scalar product) of two vectors A·B, apply to vectors in any dimension, while identities that use the cross product (vector product) A×B only apply in three dimensions, since the cross product is only defined there.

5. Exponentiation - Wikipedia

   en.wikipedia.org/wiki/Exponentiation

   When an exponent is a positive integer, that exponent indicates how many copies of the base are multiplied together. For example, 3 5 = 3 · 3 · 3 · 3 · 3 = 243. The base 3 appears 5 times in the multiplication, because the exponent is 5. Here, 243 is the 5th power of 3, or 3 raised to the 5th power.

6. Computational complexity of mathematical operations - Wikipedia

   Graphs of functions commonly used in the analysis of algorithms, showing the number of operations versus input size for each function. The following tables list the computational complexity of various algorithms for common mathematical operations.

7. Addition-chain exponentiation - Wikipedia

   en.wikipedia.org/wiki/Addition-chain_exponentiation

   Using the form of the shortest addition chain, with multiplication instead of addition, computes the desired exponent (instead of multiple) of the base. (This corresponds to OEIS sequence A003313 (Length of shortest addition chain for n).) Each exponentiation in the chain can be evaluated by multiplying two of the earlier exponentiation results.
