A new requirement that high school students in Arizona will need an extra year of math to graduate is causing anxiety among some students.

The Arizona Republic reports that beginning with the Class of 2013, students will need four years of math to graduate, up from three years.

The increased requirements are part of a state and national push by education advocates to better prepare students for college and the workforce.

The belief is that students need more rigorous math to help them solve increasingly complex problems in a technological world.

Educators say math sharpens analytical skills and helps people navigate everyday life.
