Notes: I want students to see that there are two different ways of approaching a problem such as this: with scalar math and with complex number math. If students have access to calculators that can do complex-number arithmetic, the “complex” approach is actually simpler for series-parallel combination circuits, and it yields richer (more informative) results.
11. BaCl2 + Na2SO4 → BaSO4 + NaCl 12. CrBr3 + Na2SiO3 → Cr2(SiO3)3 + NaBr Not all equations can be easily balanced by the method used here. In some equations the oxidation numbers of some atoms change during the reaction. Such equations are known as oxidation-reduction equations and many of these require special methods to balance them.

- Systems of Linear Equations Computational Considerations. One of the most important problems in technical computing is the solution of systems of simultaneous linear equations. In matrix notation, the general problem takes the following form: Given two matrices A and b, does there exist a unique matrix x, so that Ax= b or xA= b?
- This gives two possibilities r+1 = 18s^3 , r-1 = 4t^3 or r+1 = 36s^3 , r-1 = 2t^3 In the first case we can substract the two equations to give 2=18s^3-4t^3, which is the same as 1 = 9s^3 - 2t^3, clearly impossible (mod 9). In the second case we have 2 = 36s^3 - 2t^3, which is the same as 1 + t^3 = 18s^3.
- The problem tells us that there is an arithmetic sequence with two known terms which are {a_5} = - 8 and {a_{25}} = 72. The first step is to use the information of each term and substitute its value in the arithmetic formula. We have two terms so we will do it twice.
