Linear equations from graphs. Like it sounds, we will use the graphs of linear equations to produce the equation itself, using the slope intercept method (y = mx + b). Using this method we will first determine the y intercept, and then the gradient of the equation.
This is part of a series of videos looking at linear equations.

Vedic Maths is series of mathematical tricks, originating in a book written by an Indian monk Swami Bharati Krishna Tirtha in 1965. It contained a list of mental calculation techniques which were claimed to be retrieved from the Vedas - are a large body of religious texts originating in ancient India.
Please if you are learning this, however, do not treat multiplication as a mere trick. It is important to remember 17 x 13 for example, is the repeated adding of 17, 13 times (17 + 17 + 17 + 17...).
This method is a shortcut, but as the end proof shows, it is using a shuffling of required calculations to make this multiplication more efficient.
For 17 x 13, we have lots of multiplication going on (that is repeated addition!) - 10 x 10 and 3 x 10 and 7 x 10 (lots of 10s - 20 all up) - and 7 x 3.

This amazing multiplication trick possible has it's origins in Japan -although I have heard arguements it is a Vedic math trick.

Either way - this trick allows you to multiply two numbers quickly and accurately, using a handy visual method - lines.

This method does not use any multiplication tables, making it accessible to all learners.

Part 2 of this video (how to multiply using lines with fives and zeros) is here:

How Many Faces, Edges And Vertices Does A Sphere Have?
Here we’ll look at how to work out the faces, edges and vertices of a sphere.
We’ll start by counting the faces, these are the flat surfaces that make the sphere. A sphere has 0 faces altogether - but it does have a curved surface.
Next we’ll work out how many edges the sphere has, which are where two faces meet. A shere has 0 edges.
Next we’ll count the corners of the sphere (the corners). No surprises, a sphere does not have any vertices.

How Many Faces, Edges And Vertices Does A Cylinder Have?
Here we’ll look at how to work out the faces, edges and vertices of a cylinder.
We’ll start by counting the faces, these are the flat surfaces that make the cylinder. A cylinder has 2 faces altogether - 2 circular faces, as well as 1 rectangular face.
Next we’ll work out how many edges the cylinder has, which are where two faces meet. A cylinder has 2 edges.
Next we’ll count the corners of the cylinder (the corners). No surprises, a cylinder does not have any vertices.

How Many Faces, Edges And Vertices Does A Rectangular Prism Have?
Here we’ll look at how to work out the faces, edges and vertices of a rectangular prism.
We’ll start by counting the faces, these are the flat surfaces. A rectangular prism has 6 faces altogether - all rectangular in shape.
Next we’ll work out how many edges the rectangular prism has, which are where two faces meet. A rectangular proven has 12 edges.
Next we’ll count the corners of the rectangular prism (the corners). Altogether it has 8.
