In this blog, I will outline the five most common numerical mistakes I’ve seen made by students of all levels – be it primary school students in their SATS or secondary school students in their non-calculator GCSEs. I will explain why people get it wrong so often, how you avoid… Continue reading 5 common numerical mistakes – don’t make these!
In previous blogs, we’ve looked at some interesting integer sequences. We’ve looked at the Fibonacci sequence, the Look-and-say sequence, Golomb’s sequence, Van Eck’s sequence and the Lazy Caterer’s sequence. Today, we’re looking at the Kolakoski Sequence.This fun sequence can be found on the Online Encyclopedia of Integer Sequences here. The… Continue reading The Kolakoski Sequence
Standard deviation is the process that involves calculating the squared difference between each data point and the mean, summing those squared differences, dividing by the number of data points, and then taking the square root of the result. Standard deviation is useful in various fields, such as statistics, finance, and… Continue reading Mastering standard deviation: a step-by-step guide
In the previous blog, I explained the difference between simple and compound interest. In this blog, I will show you how to make use of multipliers to answer compound interest questions efficiently. I will also introduce the concept of depreciation and show how you can use multipliers to answer those… Continue reading How to use multipliers
In both the foundation and higher tiers of GCSE maths, interest questions come up fairly regularly. You will need to be able to apply two different types of interest – compound and simple. In this blog I will explain the difference between the two methods by way of an example.… Continue reading The difference between simple and compound interest
