Education Changes Everything
We built VastCalc because we believe everyone deserves access to good tools for learning. These are the organizations doing the hard work of making that belief a reality.
Why This Matters to Us
A student who understands percentages can comparison shop and avoid predatory loans. A student who understands statistics can tell the difference between a real trend and a misleading headline. A student who understands compound interest will start saving ten years earlier than one who does not. Math is not abstract. It is the most practical skill there is.
But access to quality math and science education is not evenly distributed. Your zip code, your family's income, and the color of your skin still predict how much math you will learn in school. That is not acceptable, and it is not inevitable. The organizations below are proving that every single day.
We are a calculator website. We are not going to pretend that is the same as running a nonprofit or teaching a classroom full of kids. But we can use our platform to point people toward the organizations that are doing that work, and we can make sure our own tools stay free and accessible to anyone who needs them.
Organizations We Support
Khan Academy provides free, world-class education for anyone, anywhere. Their math content spans everything from early arithmetic through calculus and statistics, with interactive exercises, videos, and an AI-powered tutor. Millions of students use Khan Academy every day, and it has never charged a dime.
Why we chose them: Math is the foundation for every calculator on VastCalc. Khan Academy makes that foundation accessible to any student with an internet connection, regardless of their school district's budget or their family's income. That is exactly the kind of impact we want to amplify.
Visit Khan AcademyCode.org is on a mission to give every student in every school the chance to learn computer science. They provide free curriculum for K-12 teachers, organize the annual Hour of Code campaign, and have helped pass computer science education policies in all 50 states. Over 80 million students have participated in their programs.
Why we chose them: Computer science runs on math. The logical thinking, problem-solving, and quantitative reasoning that students develop through calculators and math tools are the same skills that make them successful programmers. Code.org is building the pipeline.
Visit Code.orgBlack Girls CODE introduces girls of color ages 7 to 18 to computer science and technology through workshops, summer camps, and after-school programs. They teach robotics, AI, web development, mobile apps, and game design in cities across the US, and have reached over 30,000 girls since 2011.
Why we chose them: Representation matters. When young girls see people who look like them building technology, it changes what they believe is possible for their own futures. Black Girls CODE is not just teaching skills. They are reshaping who gets to participate in the tech economy.
Visit Black Girls CODEMATHCOUNTS runs engaging math programs for middle school students across the United States. Their flagship competition series takes students from school-level contests all the way to nationals, while their free Math Club program brings collaborative problem-solving to classrooms everywhere. They reach over 100,000 students annually.
Why we chose them: Middle school is where most people decide whether they are a "math person" or not. MATHCOUNTS meets students at that critical moment and shows them that math can be challenging, social, and genuinely fun. That shift in attitude lasts a lifetime.
