I am an adult and a life-long learner living in the USA who likes helping others with math & programming. I studied math and computer programming in college several decades ago, and worked as a mainframe programmer in the 1990s. I did some KA caption transcription under Josh ~10 years ago, and some DGPE (JavaScript project evaluations) under Inger ~5 years ago. https://www.khanacademy.org/profile/JaniceHolz/
