Shahriyar HajghassemHost: Shahriyar is a Maths Teacher at a School in Northwest London, teaching years 7 to 11. He graduated from the University of Warwick in 2013 and set off to China for two years teaching IGCSE and A-Level Economics.

When an equation has one variable, it can be solved using standard algebraic procedures. However, where there are two or more variables, simultaneous equations can be used to solve for both variables. In this class, students will gain a better understanding of what simultaneous equations are and how to apply them to a range of problems including geometric problems.  This class is aimed at Years 7 - 9 but is a great revision tool for GCSE students as simultaneous equations appear in both the higher and foundation curriculum at GCSE level.
