You’ve mastered adding, subtraction, divide and multiple and you feel like you can take on the mathematical world. Then you go to Secondary School and the world of numbers suddenly decides to add a whole new level of difficulty. Now there are letters involved and weird phrases that you need to remember. It might be that you need a Gloucester Maths Tutor to help you get to grips with Maths. What was the point of it all you might ask, it’s not like you were ever going to become a theoretical physicist anyway. What were the things you learnt and have probably already forgotten? Let’s start with a big one.
- Algebra. I’ll give you an easy one to start. If 20 – x = 5 what is x? The answer should be “x is a letter what the heck is it doing there amongst all those numbers?” rather than 15. Algebra is actually a bit fun and you need to have the number expressed as a letter as you need to find it with the maths you have. Just ask Sheldon Cooper, he is a bit more complicated than that. Even so it’s unlikely that you’ll be faced with having to find numbers in everyday jobs via investigative method.
- Fractions. Percentages are important, especially when it comes to figuring out your mortgage or tax. However I would expect that you have never come across it expressed as a fraction. They are sort of the same thing but being told you have a 5th eighths’ of your mortgage to pay is harder to imagine so we don’t use them. Which begs the question why bother.
- Trigonometry. This will bring back memories of SOCATOH the joys of Sin, Cosine and Tangent. Unless you were planning to become an architect or civil engineer, and at 13 I’m sure this was your driving motivation, then there was a tendency to switch off. It’s all about the angles with trig and what they do with the angles. If you like Trig you are basically living in a world of triangles.
- Geometry. Time to get a little relative here and finally get the protractor and compass out. This helps us with the area and length and volume. Actually this is quite useful and it will help you with decorating and getting round those difficult areas like the radiators. Or you could just bodge it like the rest of us.
- The Fibonacci sequence. I’m not sure but I do know it was set up by some Italian guy in 1202 to explain the development rates of rabbits using techniques from India and the Middle East. That’s bound to help you with the weekly food budget.
