New GCSE Maths 9-1 BIDMAS and LCM/ HCF revision

January 7, 2018

At York Maths Tutor we look to provide the very best one to one Maths tuition to all of our students in York. As part of this we are developing new content aimed at all of the different GCSE Maths topics. This week’s topics of interest are BIDMAS/ BODMAS and LCM and HCF.

 

LCM stands for lowest common multiple. This is one of the first topics at GCSE Maths that students are introduced to. It is a reasonably straight forward topic but people often forget the methods so it is always a good one to revise. If you are looking for LCM revision questions or worksheets then click this link.

 

HCM is highest common factor. The usual method to find the HCM of two numbers is to produce prime factor trees which can also be used to show a number as a product of its prime factors. If you want to practise more HCF worksheets visit Maths Made Easy.

 

BIDMAS or BODMAS stands for brackets, indices, division, multiplication, addition, subtraction. It is used to tell you what order to complete an equation in. BIDMAS comes up in many topics and is really important within algebra subtopics such as substitution and sequences if you are using a quadratic nth term to find a number in a sequence for instance. To practise BIDMAS questions visit this dedicated page.

 

Whatever GCSE maths topics is being revised, if your child is struggling with it, contact York Maths Tutor and we will happily arrange some additional support in the form of a private GCSE Maths tutor in York.
