Mon, 13 May 2019 21:32:44 +0000https://stalbans-mathstutor.co.uk/?p=950All straight line graphs can be written in the form of y = mx + c. Remember the number in front of x represents the gradient and c represents where the line cuts through the y axis . Lines that are parallel have the same gradient. Lines that are perpendicular have gradients that multiply together to give -1.

Thu, 02 May 2019 22:48:15 +0000https://stalbans-mathstutor.co.uk/?p=936In order to maximise your marks it is essential to show the examiner your workings. Method marks are awarded even if your final answer is incorrect. Two thirds of the new GCSE math examination is calculator based. Student often feel that they do not need to show their workings when using a calculator however this is not true. It is easy to make a mistake when using a calculator so it is really important to show the examiner what you have done.

Wed, 01 May 2019 20:16:27 +0000https://stalbans-mathstutor.co.uk/?p=933In your exam you may be asked to find the Lowest Common Multiple of two numbers. The easiest way to do this is to follow this process. First of all find the highest common factor of both numbers. Second multiply the two numbers you were given in the question. Third, divide your answer by the highest common factor and you will have found the lowest common multiple. For example find the Lowest Common Multiple of 16 and 40. First find the HCF of 16 and 40 which is 8. Now multiply 16 and 40 which is 640. Now divide 640 by 8 to give you the LCM which is 80.
]]>Remember to revise formulas!!!!!

Fri, 26 Apr 2019 22:53:14 +0000https://stalbans-mathstutor.co.uk/?p=930It is so easy to get carried away with your revision that you forget to revise the essential maths formulas. Since 2017 all formulas have been removed from the examination paper in order to make the exams more rigorous. Learning the essential formulas will enable you to access more questions in the exams and ultimately obtain a higher grade.

https://stalbans-mathstutor.co.uk/how-to-divide-by-decimals/
Thu, 25 Apr 2019 21:21:26 +0000https://stalbans-mathstutor.co.uk/?p=928Students often struggle on the non calculator paper when asked to divide a number by a decimal. There are several ways in which this can be done. But perhaps the easiest method is as follows. If you are asked to divide 400 by 0.2 what can you do? Firstly multiply both numbers by 10. 400 x 10 = 4000 0.2 x 10 = 2. We can now divide 4000 by 2 which is 2000 and that is your answer. In other words 400 divided by 0.2 = 2000.

Wed, 24 Apr 2019 22:24:03 +0000https://stalbans-mathstutor.co.uk/?p=925 Examiners often complain about the lack of structure and coherence found in students work. Far too often students will attempt a 4 or 5 mark question without first considering what pieces of information are required in order to be able to answer the question. In maths it is essential when answering a 4 or 5 mark question that you plan your answer by working in logical steps that can easily be followed. In this way you be able to gain marks even if your final answer is incorrect.
]]>28 Days To Go!!!
https://stalbans-mathstutor.co.uk/28-days-to-go/
Tue, 23 Apr 2019 20:49:38 +0000https://stalbans-mathstutor.co.uk/?p=923It is exactly 28 days (four weeks) to go before GCSE Maths Paper 1. At this time we are constantly asked the same question. “How much time should I spend revising maths each day?” The key to maths revision is repetition and practice. At this stage we think that students should be dedicating 30 minutes a day doing maths revision. This could be in the form of working through past paper, designing revision cards for topics that you may be struggling on or revising the essential formulas that you need to know for the exam.

Wed, 20 Feb 2019 23:36:45 +0000https://stalbans-mathstutor.co.uk/?p=894There are 95 girls and 87 boys in Year 12 at a school. One girl is to be chosen for the role of Head Girl. A different girl is to be chosen for Deputy Head Girl. One boy is to be chosen for Head Boy. A different boy is to be chosen for the role of Deputy Head Boy. Work out how many different ways this can be done.

Answer to yesterday’s question 360 divided by number of sides = the size of the exterior angle.
