Algebra is the branch of mathematics that studies certain abstract systems, known as algebraic structures, and the manipulation of expressions within those systems. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations, such as addition and multiplication.
For many students, passing algebra is often a Herculean challenge, [8] [10] [11] so much so that many students have dropped out of high school because of it. [8] The greatest obstacle for excelling in algebra is fluency with fractions, something many Americans do not have. [9]
The general consensus of large-scale studies that compare traditional mathematics with reform mathematics is that students in both curricula learn basic skills to about the same level as measured by traditional standardized tests, but the reform mathematics students do better on tasks requiring conceptual understanding and problem solving.

Also called infinitesimal calculus A foundation of calculus, first developed in the 17th century, that makes use of infinitesimal numbers. Calculus of moving surfaces an extension of the theory of tensor calculus to include deforming manifolds. Calculus of variations the field dedicated to maximizing or minimizing functionals. It used to be called functional calculus. Catastrophe theory a ...
In 2010, Texas Commissioner of Education Robert Scott announced the successor to the TAKS, STAAR. The STAAR had intensified rigorousness and end-of-course assessments, instead of a unified 9th, 10th, and 11th-grade Mathematics, ELA, Science, and Social Studies test. Therefore, one would take an Algebra I test in order to pass Algebra I, and so on.
In plain text, the TeX mark-up language, and some programming languages such as MATLAB and Julia, the caret symbol, ^, represents exponents, so x 2 is written as x ^ 2. [ 8 ] [ 9 ] In programming languages such as Ada , [ 10 ] Fortran , [ 11 ] Perl , [ 12 ] Python [ 13 ] and Ruby , [ 14 ] a double asterisk is used, so x 2 is written as x ** 2.
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.
Polynomial transformations have been applied to the simplification of polynomial equations for solution, where possible, by radicals. Descartes introduced the transformation of a polynomial of degree d which eliminates the term of degree d − 1 by a translation of the roots. Such a polynomial is termed depressed. This already suffices to solve ...
