In mathematics, an expansion of a product of sums expresses it as a sum of products by using the fact that multiplication distributes over addition. Expansion of a polynomial expression can be obtained by repeatedly replacing subexpressions that multiply two other subexpressions, at least one of which is an addition, by the equivalent sum of products, continuing until the expression becomes a ...
The apparent plural form in English goes back to the Latin neuter plural mathematica , based on the Greek plural ta mathēmatiká (τὰ μαθηματικά) and means roughly "all things mathematical", although it is plausible that English borrowed only the adjective mathematic(al) and formed the noun mathematics anew, after the pattern of ...
A Laurent series is a generalization of the Taylor series, allowing terms with negative exponents; it takes the form = and converges in an annulus. [6] In particular, a Laurent series can be used to examine the behavior of a complex function near a singularity by considering the series expansion on an annulus centered at the singularity.
In the equation 7x − 5 = 2, the sides of the equation are expressions.. In mathematics, an expression is a written arrangement of symbols following the context-dependent, syntactic conventions of mathematical notation.
What Works Clearinghouse ( or WWC ) [4] reviewed the evidence in support of the Everyday Mathematics program. Of the 61 pieces of evidence submitted by the publisher, 57 did not meet the WWC minimum standards for scientific evidence, four met evidence standards with reservations, and one of those four showed a statistically significant positive effect.
NAEP's category of "proficient" on a math test given to eighth graders reflects students who do well on the test and are at twelfth grade level. [25] The fact that few eighth graders are proficient by this standard and achieve at twelfth grade level has been misinterpreted to allege that few eighth graders achieve even at eighth grade level. [26]
Animation showing the use of synthetic division to find the quotient of + + + by .Note that there is no term in , so the fourth column from the right contains a zero.. In algebra, synthetic division is a method for manually performing Euclidean division of polynomials, with less writing and fewer calculations than long division.
STAR Reading, STAR Early Literacy and STAR Math are standardized, computer-adaptive assessments created by Renaissance Learning, Inc., for use in K–12 education. Each is a " Tier 2 " assessment of a skill (reading practice, math practice, and early literacy, respectively that can be used any number of times due to item-bank technology.
