This week we have been investigating square and cubed numbers as well as their notations.
A square number is simply a number that is multiplied by itself. 25 is a square number as it is the produce of 5 x 5. Square numbers are written with a small 2 in the right hand corner.
A cubed number is the result when a number is multiplied by itself twice. The symbol for cubed is a small 3 to the right of the number. They are called cubed numbers because they can also be used to calculate the volume of a cube: since a cube is a 3d shape.
