GCSE algebra

1. Factorising

2. Solving equations

3. Travel graphs

4. Algebraic fractions

5. Gradients and graphs

6. Equations of a straight line

7. Simultaneous equations

8. Inequalities

9. Indices

   • Indices show us how many times a number should be used to multiply itself E.g. 4² = 4x4 where the ² is and indices. This is the same in algebra where y² = yxy.
     • When multiplying indices add them together - Y²xY¹= (2+1) =Y­­³
     • When dividing indices subtract them - Y³/Y²= (3-2) =Y­¹
     • When raising to a power multiply them together (Y²)¹= (2x1) =Y²

10. Quadratic equations
