2. Exponentiation - Wikipedia

   en.wikipedia.org/wiki/Exponentiation

   In mathematics, exponentiation, denoted b n, is an operation involving two numbers: the base, b, and the exponent or power, n. [1] When n is a positive integer, exponentiation corresponds to repeated multiplication of the base: that is, b n is the product of multiplying n bases: [1] = ⏟.

3. Proof of Fermat's Last Theorem for specific exponents

   en.wikipedia.org/wiki/Proof_of_Fermat's_Last...

   The multiplication of two odd numbers is always odd, but the multiplication of an even number with any number is always even. An odd number raised to a power is always odd and an even number raised to power is always even, so for example x n has the same parity as x. Consider any primitive solution (x, y, z) to the equation x n + y n = z n.

4. Elementary matrix - Wikipedia

   en.wikipedia.org/wiki/Elementary_matrix

   Left multiplication (pre-multiplication) by an elementary matrix represents elementary row operations, while right multiplication (post-multiplication) represents elementary column operations. Elementary row operations are used in Gaussian elimination to reduce a matrix to row echelon form.

5. Tetration - Wikipedia

   en.wikipedia.org/wiki/Tetration

   In 2017, it was proven [14] that there exists a unique function F which is a solution of the equation F(z + 1) = exp(F(z)) and satisfies the additional conditions that F(0) = 1 and F(z) approaches the fixed points of the logarithm (roughly 0.318 ± 1.337i) as z approaches ±i∞ and that F is holomorphic in the whole complex z-plane, except the ...

6. Gaussian elimination - Wikipedia

   en.wikipedia.org/wiki/Gaussian_elimination

   Animation of Gaussian elimination. Red row eliminates the following rows, green rows change their order. In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of row-wise operations performed on the corresponding matrix of coefficients.

7. Exponential function - Wikipedia

   en.wikipedia.org/wiki/Exponential_function

   In mathematics, the exponential function is the unique real function which maps zero to one and has a derivative equal to its value. The exponential of a variable ⁠ ⁠ is denoted ⁠ ⁡ ⁠ or ⁠ ⁠, with the two notations used interchangeably.

8. Distributive property - Wikipedia

   en.wikipedia.org/wiki/Distributive_property

   To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted). If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks ...

9. Matrix exponential - Wikipedia

   en.wikipedia.org/wiki/Matrix_exponential

   Multiply each exponentiated eigenvalue by the corresponding undetermined coefficient matrix B i. If the eigenvalues have an algebraic multiplicity greater than 1, then repeat the process, but now multiplying by an extra factor of t for each repetition, to ensure linear independence.
