St(P) Mathematics 3a2nd Ed.

Description: Part of the ST(P) graded series in mathematics, this book follows 1A and 2A and completes coverage of Levels 6 and 7 of the National Curriculum, and most of Level 8. Some of the work goes beyond Level 8. In particular, there is a large section on algebra which starts the preparation for the skills needed to cope with the algebra content of Level 10. The exercises are divided into three types of question. The first kind is aimed at helping pupils to understand the work, the second is for quicker workers, for extra practice or for later revision and the third is slightly more difficult, for those who have managed the first type fairly easily. Table of Contents: Making sure of arithmetic; equations, inequalities and formulae; sequences; matrices; percentages; straight line graphs; simultaneous equations; inverse and square matrices; areas; angles in circles; algebraic products; algebraic factors; quadratic equations; graphs; polygons; probability; ratio and proportion; trigonometry; Pythagoras' Theorem; three-figure bearings; inequalities and regions; co-ordinates in three dimensions; algebraic fractions; loci; plans and elevations; statistics.
