This chapter focuses on simplifying expressions. It covers adding together simple lists of letters and numbers including negatives in the list. And lastly multiplying and dividing simple algebraic expressions. Algebra is a very important...
When you take a fraction such as y = f(x) or between two limits on the x-axis and rotate this part of the curve around the x-axis the shape formed will be a 3...
This chapter covers distance-time graphs. It explores how to draw and interpret distance-time graphs. Having prior knowledge of gradient of a straight line and speed will be very useful here. What is kinematics Kinematics...
This article explores cancelling algebraic fractions. It covers cancelling down algebraic fractions including brackets. Prior knowledge of factorisation and expanding will be useful in this article When working with fractions you can sometimes divide...
This section explores adding algebraic fractions. It covers adding algebraic fractions with a single term in the denominator, adding fractions with linear denominators, adding fractions with quadratic denominators which will be quite advanced for...
This chapter explores rules and formulae. It covers using letters to represent unknown numbers, substituting numbers into simple expressions and formulae and understanding basic fomulae. Fomulae contain letters which represent unknown values. The values...
