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!

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.

Food Rations from the 19th century to the present day.
Meal, Ready-to-Eat
The modern ration has been refined over many years and various conflicts to be both nutritionally balanced and contain all the calories a soldier requires when in the field, with one MRE bag containing approximately 1250 calories. In addition to this, the MRE has been designed to fulfil all operational requirements. This means that they remain shelf stable for a minimum of three years, or nine months in warmer climates. They also are highly durable and have the ability to survive non-parachute drops of 100 feet and parachute drops of 1250 feet. With all these elements considered, a soldier can eat a full, nutritional meal wherever they find themselves.

The combat experience in Poland and France showed that soldiers using methamphetamine were showing clear signs of superiority in combat. They fought without fear and, above all, didn’t get tired. The case, however, also showed the harmful effects of the stimulant. Its excessive use led to physical and mental exhaustion, as Reich Health Führer warned in 1939. These negative side effects led to the ban of Pervitin by the Reich Opium Law in June 1941.

This trigonometry video tutorial provides a basic introduction into radians and degrees. It explains the definition of the radian and how to calculate the angle measure in radians given the arc length of a circle and the length of the radius. This video also explains the process of converting degrees to radians and converting radians to degrees. To convert from degrees to radians, multiply the angle measure in degrees by pi divided by 180. To convert from radians to degrees, multiply the radian measure by 180 over pi. To calculate the angle measure in radians - divide the arc length by the length of the radius of the circle. This video also explains how to draw angles in standard position using radians instead of degrees. It explains the location of common angles such as pi/4, 3pi/4, 5pi/4, and 7pi/4 and more. This video contains a lot of examples and practice problems.

Inches, Feet and Yards - Estimating Length | Measurement for Kids | 2nd Grade Math
Install now Kids Academy Talented & Gifted: https://smart.link/5d9b5460c7805
If there is a distance, we find the length of it. We want to know how far a thing is or what’s the length of it. Now length can be measured in three different terms, which are inches, feet, and yard. So, what are these inches, feet, and yards?
These are simply the terms in which we define the length of something. All of them are interrelated with each other.
These terms can be defined in terms of each other.
To put it simply, 12 inches=1 foot and 1 yard= 3 feet. Inch is the smallest term. An inch can be measured in terms of centimeters but that is another term to learn. Simply speaking the distance between your thumb to your knuckle is about 1 inch. The bottle cap is also about 1 inch. So, inch is a very small unit.
These terms help to measure the length and distances. These are very basic measuring terms that the kid must know about in their initial maths lessons.
