Instamath is a not-for-profit company created by five students to promote mathematics learning through Instagram. By uploading math problems, explanations, and live sessions, they aim to make math more engaging and help students struggling with different concepts. As an online company, they can work remotely but use their school for materials. Their roles are divided between managing the profile, publicity, uploading problems, and live sessions. They plan to attract over 1,000 followers and then generate income from advertisers to reinvest in the company.
