Intelligence is defined as general cognitive problem-solving skills involving reasoning, relationships, and learning. It can be divided into seven subcategories: musical, bodily-kinesthetic, logical-mathematical, linguistic, spatial, interpersonal, and intrapersonal. While intelligence is inherited, environment also influences its expression. It can be increased through problem-solving, creativity, and decision-making tools. Having strong emotional skills relates to better mental health and academic performance by allowing students to cope with stress and difficulties.
