Calc Chat began in 2002 as a way to assist students all over the country who were struggling with mathematical concepts. We offer FREE worked-out solutions to all odd numbered exercises from any textbook by Ron Larson.

For the past 9 years students who needed extra help have been able to chat live with a tutor or other students for a small fee. We recognize a need for students to develop strong math skills, so the chat portion of the site is now FREE as well.

Math tutors are available Sunday - Thursday from 4:00 pm to midnight.

During summer months, hours change to Monday - Friday from 1:00 pm to 4:00 pm.
