You’ve probably come across the 3 different measures of average
4, 6, 6, 7, 10, 11, 12
Mean = 8
Median = 7
Mode = 6
The range also often gets added onto these 3… although it isn’t actually a measure of the average. It’s the difference between the largest and smallest value in the data.
So the range here is 12 subtract 4, which is 8
4, 6, 6, 7, 10, 11, 12
Mean = 8
Median = 7
Mode = 6
RANGE = 12 - 4 = 8
The range provides context for the mean, median and mode. If the range is large, then the mean median or mode might not represent the data very well. Whereas if the range is small, then they will represent the data well. In this video, we learn all about The Range in more detail.

Algebraic fractions are simply fractions with algebraic expressions either on the top, bottom or both. We treat them in the same way as we would numerical fractions.
In this video we look at how to simplify algebraic fractions, and how to add and subtract them.

The word polygon comes from Greek. Poly means “many” and Gon means “angles”. Polygon = many angles. Polygons are 2-dimensional shapes, that are made of straight lines, with all the sides joined up.

In algebra we have lots of different names for different things: expressions, equations, formulae and identities are all slightly different versions of similar things. Then within these, we have variables, constants, coefficients and exponents to describe the different parts. We also need to know wh
