Learn how you can square large numbers in your head - instantly! This easy to learn technique will have you calculating the square of numbers up to 100 - without the need for a calculator.
The trick is easy - first we find the distance from the number being squared to the nearest tens number. Say for example we are trying to find the square of 23 - the nearest tens number is 20, which is 3 away from 23. So 3 is our result!
We use this number to find the square - by taking this number from the number being squared (23 - 3 = 20) and then adding this number to the number being squared (23 + 3 = 26). We easily multiply these two numbers (20 x 26 = 520).
To this we add our distance number squared (3 x 3 = 9). So we add 9 to 520...our answer is 529.
Love the math!
The old math is dead! Long live the math!

How Many Faces, Edges And Vertices Does A Cube Have?
Here we’ll look at how to work out the faces, edges and vertices of a cube.
We’ll start by counting the faces, these are the flat surfaces that make the cube. A cube has 6 faces altogether - all square in shape.
Next we’ll work out how many edges the cube has, which are where two faces meet. A cube has 12 edges.
Next we’ll count the corners of the cube (the corners). Do that and you'll get 8.

For the full playlist for the faces, edges and Vertices of a whole lot of 3D shapes go to https://www.youtube.com/playli....st?list=PLjbxBzUM6SL
