Product Description
A poster explaining index notation.
Information on poster includes:
Index notation is a short way of writing a number being multiplied by itself several times.
The number that is being multiplied by itself is known as the ‘base’.
The number written above the base is known as the ‘index’, ‘power’ or ‘exponent’.
The index is the number of times that the base must be multiplied by itself.
53 is read as ‘5 to the power of 3’ or simply ‘5 cubed’.

A poster explaining expanded notation.
Information on poster includes:
Expanded notation is writing a number to show the value of each digit. It represents a number as the sum of each of its digits multiplied by their place value (ones, tens, hundreds etc.)
For example: 384 = 3 x 100 + 8 x 10 + 4 x 1
= 300 + 80 + 4
= 384
Expanded notation can also be used when working with powers of 10.
100 = 10 x 10
1 000 = 10 x 10 x 10.
