Algebra I on Khan Academy: Algebra is the language through which we describe patterns. Think of it as a shorthand, of sorts. As opposed to having to do something over and over again, algebra gives you a simple way to express that repetitive process. It's also seen as a "gatekeeper" subject. Once you achieve an understanding of algebra, the higher-level math subjects become accessible to you. Without it, it's impossible to move forward. It's used by people with lots of different jobs, like carpentry, engineering, and fashion design. In these tutorials, we'll cover a lot of ground. Some of the topics include linear equations, linear inequalities, linear functions, systems of equations, factoring expressions, quadratic expressions, exponents, functions, and ratios.
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This physics video tutorial explains how to solve any resistors in series and parallel combination circuit problems. The first thing you need to do is calculate the equivalent resistance of the circuit which you can use to calculate the current flowing from the battery based on ohm's law. Using the current and the voltage drops across each resistor, you can calculate the electric potential at every point in the circuit which will allow you to calculate the current flowing through any resistor. This technique is useful if there's not multiple batteries in different loops of the equation. Keep in mind, the current flowing in two resistors that are in series with each other is the same. The voltage is the same across resistors connected in parallel. This video contains plenty of examples and practice problems including a current division formula for resistors connected in parallel.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

Figures in History: Otto von Bismarck (1815–1898)
Otto von Bismarck was responsible for transforming a collection of small German states, unifying them into the German empire, and becoming its first chancellor. His diplomacy of realpolitik and powerful rule gained him the nickname of the "Iron Chancellor."

En este video para aprender español aprenderemos vocabulario sobre las diferentes partes de una casa.
Veremos como se llaman las diferentes partes del interior de una casa y los elementos que la componen.
El salón: https://youtu.be/wcVkIWffI84?t=127
En es salón es donde se suele pasar la mayor parte del tiempo en las casas. Suele haber sofás para ver la tele y pasar el rato en familia. Además de sofás y televisión suele haber alguna mesa baja para apoyar cosas, como pizza!
La cocina: https://youtu.be/wcVkIWffI84?t=234
Tiene el espacio suficiente para poder comer en familia. A Carlos le encanta hacer paellas en la cocina. Suele tener una mesa y muchos armarios para guardar las cosas, además del horno, la nevera y el microondas.
El baño de los niños: https://youtu.be/wcVkIWffI84?t=336
Suele estar bastante desordenado. Tiene una bañera en la que les encanta jugar y hacer espuma. Además suele tener toallas, un inodoro y un lavatorio.
La habitación de Alejandro: https://youtu.be/wcVkIWffI84?t=376
Tiene una cama (sin hacer), un escritorio, una cómoda y muuuchos coches. También le gusta mucho leer por lo que hay varios libros.
La habitación de Aroa: https://youtu.be/wcVkIWffI84?t=424
También tiene una cama y un escritorio, pero a Aroa le encanta pintar y los peluches. Tiene una mesa de luz, un armario y una ventana por la que entra mucha luz.
La habitación principal: https://youtu.be/wcVkIWffI84?t=482
Tiene una cama de matrimonio, un vestidor y un baño privado con ducha. El vestidor esta repleto de ropa. Tiene también espacio para los ordenadores en el escritorio y un gran ventana por la que entra mucha luz.
En este vÃdeo anterior puedes ver el exterior de la casa: https://youtu.be/YFSMY2ECYco

Mathematical discoveries happen every day. PEMDAS wasn’t even a thing until the 1900s! In this K12 Teaching Moment, our host, David, will walk you through the order of operations and how it became standardized across the world.
Scroll down to see the answer and how it is solved...
How to Solve: 20 − 5 ÷ (2+3)
Step 1: Solve what is in the parentheses (PEMDAS) first, so 2+3 = 5
Now the equation is 20 – 5 ÷ 5
Step 2: Do the division (PEMDAS), so 5 ÷ 5 = 1
Now the equation is 20 – 1
Step 3: Subtract the final numbers (PEMDAS), so 20 – 1 =19
And the answer is 19!
