What is problem solving?
- Problem solving in mathematics involves going through various stages to find solutions to questions.
- In the context of these notes, all problems revolve around equations, which can be linear, quadratic, simultaneous, or other relatively straightforward equations.
- You may notice there are not many subheadings in these notes
- That is deliberate so the examples are not labelled or dealt with in an order
- This is the nature of problem solving questions!
- You never know exactly what’s coming ... !
- In a typical mathematics problem, you're presented with an equation to solve. However, in problem-solving scenarios, you're tasked with creating the equation by:
- Utilizing information provided in the question.
- Employing your understanding of standard mathematical principles and outcomes.
- In problem-solving questions, it's crucial to interpret the answer within the given context:
- The numerical answer, such as "2" from a calculator, needs to be contextualized. For instance, if the question pertains to money, the final answer should be expressed as £1.20.
- Quadratic equations may yield two solutions, but only one may be applicable if only positive values are relevant, as in the case of distance.
- Problem-solving questions typically offer less specific information regarding the mathematical approach required.
- It's impractical to catalog every type of problem-solving question one might encounter, as there's a vast array of potential contexts.
- There's no universal, step-by-step method applicable to all problems. Instead, success in problem solving hinges on practice, experience, and familiarity with various problem-solving strategies.
- Do not necessarily expect whole number (integer) or “nice” solutions
- Especially where a calculator is allowed
- Rounding appropriately may be one of the skills being tested
- eg Rounding a value in cm only needs to be to one decimal place;
- so it indicates mm
