Access and scope
All six calculators are free, need no sign-up, and run right in your browser.
The grade and GPA tools use the stated assumptions rather than every school’s grading policy. The algebra tool handles supported simple linear equations, not general symbolic mathematics.
What is the best free calculator for homework?
It depends on the problem. Each of StudySim's six calculators handles one job: arithmetic, percentages, weighted grades, GPA, fractions or simple linear equations in x. They're free, need no signup, and calculate in your browser.
What is the best free app for math calculations?
For quick numbers, a browser tool saves you an install. StudySim's calculators work in the page and send no AI request. When you need the reasoning behind a word problem, the AI math tutor shows worked steps instead.
What type of calculators do schools use?
Many classes and exams require a specific handheld model, so check your course and exam rules. StudySim's calculators are study tools for homework and for checking your work. They don't replace a calculator approved for your exam.
Is there a basic calculator online for free?
Yes. The arithmetic calculator handles everyday sums in your browser with no signup and no AI allowance. See all six on the student calculators page.
