As a former Head of Mathematics, and a user of Casio calculators for over 40 years, I am confident that the fx-991EX is quite possibly the best classroom calculator they have ever produced. It retains the ease of use of the fx-83GT, but adds power and functionality that takes it literally to game-changing levels. Aimed squarely at the Secondary school market, and carefully featured to ensure that it stays within the parameters of public examination guidelines, this would be the calculator of choice for any student from Year 7 to Year 13 Further Mathematics. The only other calculator an A-Level student might need would be a graphical calculator, but the features of this one make even that an option rather than an essential. Some of the new features that make this compelling for me are as follows: NUMBER The incredibly high definition screen and multi-line display options make it easy to enter calculations and see answers in textbook style and clarity - be they with fractions, brackets, surds (roots), or any combination. The new Random Integer function makes it easy to simulate coin flips, dice rolls and even card selections or lottery draws, opening up possibilities for a huge variety of mathematical experiments and games. Factorising large numbers (up to 10 digits) into powers of prime factors with a single FACT command - amazing.

Ratio calculations (example 3:10 is equivalent to?:7) - the classic ‘Rule of Three’ which was an arithmetic nightmare to Victorian schoolchildren, is now just a tap away. ALGEBRA Incredible power to solve equations and systems of equations or inequalities. The machine will solve algebraically any polynomial equation up to 4th degree (quartics). It can’t go higher because the general 5th power (quintic) is unsolvable - see Galois Theory! However, it can find a root for any general equation using Newton-Raphson to refine a user-supplied initial approximation. Similarly systems of simultaneous equations now go up to four equations in four unknowns.

Also, by using the Inequality function on a quadratic, cubic or quartic polynomial, one can quickly find the points on the graph (if any) where it crosses the x-axis. The Solving and Inequality functions alone remove much of the need to turn to graphic calculators when working with graphs of polynomial functions. MATRICES Matrices can now be input up to 4 x 4, with the calculator happily finding determinants, sums, products and even inverses.
