Hi, I'm Peter Edwards from Bluetutors. We teach children of all ages, right from primary school to degree level, and we find the highest quality tutors. And today, I'm going to teach you some maths. We're now going to talk about what students should do to do pre-algebra. So, what they should know just before they start learning algebra. It's very very important to make sure they have a solid foundation in maths before we start introducing unknown quantities, because if not, when you start doing algebra, the student is going to get very, very confused. So, I've just bullet points here, it's a list of things really which students should know inside out before they start doing algebra. Most of you will be very, very familiar. Obviously, what we start doing, the first time we start doing maths is addition, multiplication, subtraction, and division. As with all of these, what you'll really want is to have done a number of examples in all of these things so that you're completely comfortable with it. It sounds boring, it sounds annoying, but, by doing examples, by repeating calculations over and over again, you really will get a firm grounding in these ideas. The next thing we've talked about it powers. Obviously, before students can do algebra, particularly the quadratic equation, they have to understand what a square number is; they have to understand what a square root is. These things are very, very important for students, and we should be encouraging students to practice squaring numbers, cubing numbers, even putting numbers to the power of 4. Making sure they know what that power sign means when it's up there. And, obviously, square root is something that, if they're learning the square numbers, they will also be learning the square roots as well. The last two things are fractions and decimals which, obviously, are of two very similar ideas. We really want students to understand what it means when we write, say, one over four. We want them to know that one over four means one divided by four. We also want them to know diagramatically what that means, we want them to understand what a fraction is and what it's doing in an equation. So when someone sees x over 4, they know that that is a portion of x. But yeah, so, those are the main points that we need to get across to students before they start to learn algebra. And once they are comfortable with them, by putting unknown quantities into an equation, hopefully will throw them less than if they really don't understand these. And that's how to do pre-algebra. .
