1In formal reasoning the premises is: if this is that, that must be this. In informal reasoning the premises is that there is no clearly correct solution. Formal reasoning uses deductive reasoning and algorithms while informal reasoning uses dialectal reasoning and heuristics. When using formal reasoning the number and quality of answers needed for drawing a conclusion or reaching a solution is specified clearly, and there is a single right (or best) answer. Established methods usually exist for solving the problem, and you usually know when it has been solved. Informal reasoning uses many approaches, viewpoints, and possible solutions that compete, you may have to decide which one is most reasonable. Only formal reasoning has a presence of established procedures called a algorithm, informal relies on more of a rule of thumb called a heuristic. Both formal and informal reasoning have a recognition that the problem is solved, they just go about getting the solution differently. When it comes to real world or personal
