Pre-Algebra on Khan Academy: No way, this isn’t your run of the mill arithmetic. This is Pre-algebra. You’re about to play with the professionals. Think of pre-algebra as a runway. You’re the airplane and algebra is your sunny vacation destination. Without the runway you’re not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We’re about to take off!

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.

Learn how to determine the multiple characteristics of a polynomial. A polynomial is an equation of the type y = ax^n + bx^(n-1) + cx^(n-2) + . . . + k, where a, b, c, . . ., k are constants.The highest exponent of a polynomial is called the degree of the polynomial. Given the…

► My Multiple Integrals course: https://www.kristakingmath.com/multiple-integrals-course Learn how to use midpoint rule to approximate the volume that lies above the given rectangular region defined by the given x-interval by the given y-interval, and below the given function. You’ll divide the interval into rectangles and then find the coordinate point that defines the midpoint of each…

In this, THE FIRST EPISODE of Crash Course Physics, your host Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer? And did you deserve that…
