Denne undervisningsvideo til matematik handler om, hvordan man kan løse simple ligninger, som indeholder plus- eller minus-parenteser. Du lærer at hæve parenteser, om plus- og minus-parenteser og at løse simple ligninger. Området bliver gennemgået punkt for punkt vha. en disposition.

Denne udgave en en ny version af en anden video om, hvordan man løser ligninger med plus- eller minus-parenteser, som her er tilpasset mobiltelefoner. Altså er denne video dermed en såkaldt mobilversion.

Felix og Mikkel viser hvordan man Beregner x

LIGNINGER og PARENTESER: I denne video kigger jeg på, hvorledes man løser ligninger med parenteser. Du skal stadig isolere X på den ene side og alle talene på den anden side.

Udover at behandle parenteser, så kommer videoen ind på, hvorledes du lægger X'er med hinanden fx: 3x+5x. For at det ikke skal forvirre, så kan du istedet for X blot tænke på fx bananer: 3 bananer + 5 bananer = 8 bananer. Dette er en nemmere måde at lægge X'er sammen på.

I to eksempler gennemgår vi hvordan man kan isolere variable i en ligning. Vi tager udgangspunkt i to forskellige eksempler fra fysik c undervisningen:

1) Isolere variable i Ohms lov, og
2) Isolere variablen for massen m, i den kinetiske energi

Der er lavet opgaver til videoen. Du kan hente opgaverne her - du har nærmest 100% sikkert ikke lært det, ved at se mig gøre det. Du skal selv igang :-). Heldigvis er der facit med til opgaverne:

Medforfatter: Jens Christian Hansen, der har været en stor hjælp med faglige inputs, samt opgaver, Programmør: Kristian Wichmann, der med stor tålmodighed fik hakket os igennem noget programmering, der gør det muligt at lave mange flere videoer som denne.

Lærer Tom Olav Moen viser deg hvordan du regner ligninger med én ukjent.

AREAL af en REKTANGEL og LIGNINGER: Hvis du i en opgave får oplyst arealet og blot en af siderne på en rektangel, så kan du let finde den sidste side vha. ligninger. Se videoen og lær hvordan det er muligt.

LIGNINGER: Hvordan løser man en ligning med et X?

Videoen præsenterer den letteste måde at løse ligninger på. I en ligning skal man finde den ubekendte X. Dette er muligt vha. følgende regneregler:
(+) plus bliver til minus (-)
(-) minus bliver til plus (+)
(*) gange bliver til dividere (:)
(:) dividere bliver til gange (*)

Physicists, air traffic controllers, and video game creators all have at least one thing in common: vectors. But what exactly are they, and why do they matter? David Huynh explains how vectors are a prime example of the elegance, beauty, and fundamental usefulness of mathematics.

Welcome to an introduction to economics! In a basic sense, economics is the study of the choices people make to satisfy their wants and needs with a limited supply of resources. In this video, you'll learn about the difference between wants and needs, goods and services, the concepts of resources and scarcity along with the three basic economic questions.

It’s obvious that knowing more than one language can make certain things easier — like traveling or watching movies without subtitles. But are there other advantages to having a bilingual (or multilingual) brain? Mia Nacamulli details the three types of bilingual brains and shows how knowing more than one language keeps your brain healthy, complex and actively engaged.
