Precalculus. For many high school students, it’s an intimidating subject to learn. However, a strong foundation in precalculus—which reinforces and builds upon algebra, trigonometry, and other mathematical concepts—prepares students for college and career success. IXL wants to help students feel comfortable with these challenging, higher-order math skills, so we’ve recently expanded our content to include precalculus. With this addition, students now have access to a full high school curriculum of over 975 advanced skills, presented in ways that make even the hardest math problems achievable.
