This video looks at the excitement which is whole number addition and subtraction. However, we're not going to show you how to add and subtract numbers - not at a Year 8 level!! That would be far too easy. We look at the mental techniques and how to use algorithms to find missing digits in complex addition and subtraction problems. So much fun!

This video looks not at the techniques of how to multiply and divide numbers, but how to use different techniques to do it mentally. There is also a discussion about algorithms and how we can use them to find the missing numbers in long multiplication and short division problems.

Have you ever wondered about all the wonderful properties which numbers have? Well, wonder no more as this video talks all about them. Prime numbers, composite number, HCF, LCM, Factors, Multiples, Cubes, Squares, Square roots and much more. It doesn't get more exciting than this!

Have you ever wondered what the divisibility rules are? Want to know how to find the HCF and LCM of numbers? Do you know that HCF stands for Highest Common Factor and LCM stands for Lowest Common Multiple? Want to know how to do Prime Factorisation using Factor Trees? Then this video will answer all those questions you may - or may not! - have. Lots of worked examples are provided with downloadable notes (at www.maffsguru.com).

This video recaps the work which will have been covered in previous years. It introduces what negative numbers are, it looks at the idea of number lines and temperature to describe negative numbers and then looks at simple addition and subtraction and the strategies which might be used to solve simple problems.

This video is probably one of the most important for the whole Mathematics curriculum. Negative numbers are used in every subject and topic. Being about to add and subtract negative numbers is going to be vitally important. Sadly, it's something which people find challenging! But ... hopefully not once you've watched this video. Addition and Subtraction of negative numbers can be done using "The Four Rules" which I show (with lots of examples). I also show why they work. All explained without the smoke and mirrors!

This is another really important video which builds on the previous video in this series. Being able to add and subtract negative numbers is really important, but even more important is the ability to multiply and divide them. This comes up in so many parts of the course (Mathematics!). This video looks at a lot of examples and shows how to build on the knowledge from the previous video to answer some pretty complex problems! It's really important to know how to Multiply and Divide Integers

Before we start, we need to clear up if it's BIDMAS or BODMAS. It's clearly answered in the video and then I take some time to explain how it is used. There are lots of examples which show, not only how to use BIDMAS/BODMAS but how to use it with negative numbers. The rest of the video looks at how we can use the work from Year 7 algebra alongside the new work on negative numbers and BIDMAS. This is the beauty of mathematics! There are lots of worked examples all explained in an easy to understand way.
