2. Algebraic expression - Wikipedia

   en.wikipedia.org/wiki/Algebraic_expression

   In mathematics, an algebraic expression is an expression built up from constants (usually, algebraic numbers) variables, and the basic algebraic operations: addition (+), subtraction (-), multiplication (×), division (÷), whole number powers, and roots (fractional powers).

3. Pre-algebra - Wikipedia

   Powers in scientific notation (example: 340,000,000 in scientific notation is 3.4 × 10 8) Identifying Probability; Solving Square roots; Pythagorean Theorem [4] Pre-algebra may include subjects from geometry, especially to further the understanding of algebra in applications to area and volume.

4. Algebraic operation - Wikipedia

   en.wikipedia.org/wiki/Algebraic_operation

   In mathematics, a basic algebraic operation is any one of the common operations of elementary algebra, which include addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power). [1] These operations may be performed on numbers, in which case they are often called arithmetic operations.

5. Fractional calculus - Wikipedia

   en.wikipedia.org/wiki/Fractional_calculus

   Fractional calculus is a branch of mathematical analysis that studies the several different possibilities of defining real number powers or complex number powers of the differentiation operator = (), and of the integration operator J {\displaystyle J} [ Note 1 ] J f ( x ) = ∫ 0 x f ( s ) d s , {\displaystyle Jf(x)=\int _{0}^{x}f(s)\,ds\,,}

6. Solving quadratic equations with continued fractions - Wikipedia

   en.wikipedia.org/wiki/Solving_quadratic...

   If this infinite continued fraction converges at all, it must converge to one of the roots of the monic polynomial x 2 + bx + c = 0. Unfortunately, this particular continued fraction does not converge to a finite number in every case. We can easily see that this is so by considering the quadratic formula and a monic polynomial with real ...
