Det vi kan gjøre nå, er og fortsette å legge til regneoperasjoner
•Algebra er et effektivt verktøy for å utforske, analysere og representere matematiske begreper og ideer, samt for å beskrive og modellere forhold og sammenhenger i hverdagsfenomener. •Mye av matematikken i skolen bygger på algebra. Viktig for å lykkes med vider In mathematics, an algebra over a field (often simply called an algebra) is a vector space equipped with a bilinear product.Thus, an algebra is an algebraic structure consisting of a set together with operations of multiplication and addition and scalar multiplication by elements of a field and satisfying the axioms implied by vector space and bilinear Learn algebra for free—variables, equations, functions, graphs, and more.

Den største forskjellen mellom algebra og aritmetikk er inkluderingen av variabler Algebra er regning med ukjente tall, med x-er og y-er, og er gjerne blant de grenene av matematikken vi sliter mest med på skolebenken. De internasjonale kartleggingsstudiene PISA og TIMSS, som sammenligner matteferdighetene til elever fra forskjellige land, har vist at norske elevers algebraferdigheter ligger under gjennomsnittet for OECD-land, og langt bak for eksempel finnene

An algebra is sometimes implicitly assumed to be associative or to possess a multiplicative identity.. Examples of algebras include the algebra of real numbers, vectors and matrices, tensors, complex numbers, and quaternions. (Note that linear algebra, which is the study of linear sets of equations and their transformation properties, is not an algebra in the formal sense of the word. Algebra can be a difficult subject to master. In addition to numbers, there are letters thrown into equations. These letters are called variables, and they represent unknown numbers. It may seem overwhelming at first, but by learning a few basic concepts and doing practice problems, you can be. Simply put, algebra is about finding the unknown or putting real life variables into equations and then solving them. Unfortunately, many textbooks go straight to the rules, procedures, and formulas, forgetting that these are real life problems being solved and skipping the explanation of algebra at its core: using symbols to represent variables and missing factors in equations and.
