working memory has strengths, such as the ability to recall or cue an unlimited number of facts and procedures from long-term memory for problem-solving. Therefore, while working memory has limitations when dealing with new information, these limitations disappear when dealing with previously learned information stored in long-term memory. In other words, to solve a new problem, we need connected information, and lots of it, to be stored in our long-term memory.And that means we need to learn many facts and understand how they are connected. After that, we have to practice.
