![]() ![]() Use #A# to represent Andrew's age, #B# to represent Brian's age and #C# to represent Charles's age. Grannies house sat three blocks off Magnolia Beachs main drag, and at least a dozen people had done shocked double takes as shed passed. Once you have a symbolic representation of the problem - typically in the form of a set of simultaneous equations to be solved, try eliminating variables one at a time by rearranging terms, using basic arithmetic operations and substitutions.Eventually this process will probably lead to values (or at least constraints) for all of the unknowns.Ĭonvert these values or constraints back into the context and language of the problem to express the solution.įor example, suppose Andrew is half the age of Brian, Brian is three times older than Charles and the sum of their ages is 44 years. ![]() If a mathematical problem is expressed in words, then first try to express all the relevant information in the problem in terms of symbols representing unknowns, in the form of equations, inequalities, etc. ![]()
