Need a quick math calculator for homework or exam prep? Our free tools help you solve equations, calculate areas and volumes, work with fractions, and check your math — all with step-by-step explanations showing how the answer was reached, not just the final number.
We offer specialized calculators for the most common math operations students encounter. Each calculator not only gives you the answer but shows the complete working process so you can learn the method.
Solve one-step, two-step, and multi-step linear equations. Enter an equation like 3x + 7 = 22 and get the solution with every step shown — what to subtract, what to divide, and why each step is performed.
Add, subtract, multiply, and divide fractions. Enter any two fractions and see the complete process: finding the LCD, converting, performing the operation, and simplifying to lowest terms.
Calculate the area of triangles, rectangles, circles, parallelograms, and trapezoids. Enter measurements and get the area with the formula displayed and each substitution step shown.
Find the volume of cylinders, cones, spheres, rectangular prisms, and pyramids. Our dedicated volume calculator page has individual tools for each shape with formula references and visual diagrams.
Enter two points (x₁, y₁) and (x₂, y₂) and instantly find the slope, y-intercept, equation of the line in slope-intercept form, and distance between the points. Step-by-step formula application included.
Evaluate expressions with exponents, apply exponent rules (product, quotient, power, zero, negative), and simplify expressions. Shows which rule applies at each step.
Regular calculators give you an answer. Step-by-step calculators teach you the process. Here is why that distinction matters for learning:
When you see that 3x + 7 = 22 gives x = 5, knowing the answer alone does not help you solve 4x - 3 = 17 on tomorrow's test. But when you see the steps — subtract 7 from both sides to get 3x = 15, then divide both sides by 3 to get x = 5 — you learn a transferable method that works for any equation of that form.
This is why our tools emphasize the process over the product. Every calculation shows you not just what the answer is, but how it was found and why each step was taken.

A common question students ask: DeltaMath.com itself does not have a built-in calculator (as of 2026). Whether you can use an external calculator depends entirely on your teacher's instructions. Some teachers explicitly allow calculator use for certain assignments, while others prohibit it. When in doubt, ask your teacher.
For practice on deltamath.cc, there are no restrictions — you can use whatever tools help you learn. However, we recommend solving problems without a calculator first to build mental math skills, then using our step-by-step tools to check your work and understand mistakes.

Start Free Practice →DeltaMath.com does not include a built-in calculator tool. Whether you can use an external calculator on DeltaMath assignments depends on your teacher's instructions. Our site (deltamath.cc) provides free calculator tools for practice and learning.
This depends entirely on your teacher's policy. Some DeltaMath assignments are designed to be done without a calculator to build mental math skills, while others expect calculator use. Always check with your teacher before using one.
For step-by-step solutions, our tools at deltamath.cc show the complete solving process. For graphing, Desmos is excellent and free. For advanced calculations, Wolfram Alpha is powerful but the free version has limitations.
