About Math Solver

The Math Solver gives you three ways to get to an answer. Type a problem the way you would write it on paper and it answers on this page, with the exact value, the decimal and the steps. Hand it to the AI solver, which reads a problem from a photo or works through a word problem. Or turn the Math Wheel: pick a topic, pick what you want to do, and you land on the solver built for exactly that job. Every math solver on MiniWebtool is on the wheel, more than 450 of them.

At a Glance

Math Solver answers typed problems with the exact answer, the steps and a graph, has an AI solver for photos and word problems, and its Math Wheel leads to every math solver on MiniWebtool.

How to use the Math Solver

Type the problem, or pick a topic. Type something like x^2 - 5x + 6 = 0 and press Enter for the answer with the steps. Or tap one of the twelve topics on the wheel. You can also press on the centre and flick outward toward a slice.
Pick what you want to do. The wheel turns into the jobs inside that topic, such as Solve a triangle or Percentages. The panel beside the wheel lists the solvers behind each one.
Open the solver. The wheel now shows the solvers for that job, with a line on what each one does. Press Open solver. On a phone, tap a slice once to read about it and again to open it.
Search or spin. Type part of a solver’s name, such as percent or triangle, and the matches appear as you type. Enter opens the first one. Not sure what you need? Press SPIN in the centre.
Use the AI solver. Tap Photo, the button marked AI, to have a problem read from a picture, or choose Ask a word problem beside the wheel and type it in your own words. Each AI run uses 1 AI credit.
Go back. Tap the centre of the wheel or use your browser’s Back button. Each level has its own link, so you can bookmark a topic or send it to someone.

What the AI solver does, and what is free

Most of this page does not use AI at all. A problem you type is worked out by a calculator and an algebra engine, so the arithmetic is exact, and that is free, like the graphs and the wheel. AI comes in for three things a calculator cannot do by itself, and each of them is marked AI where it starts:

AI feature	What it does	Where to find it
Photo	Reads a printed or handwritten problem from a picture or a screenshot into the input line. You check it, then the calculator solves it.	The Photo button, or Solve from a photo beside the wheel
Word problems	Turns a problem written in sentences into the math, solves it, and has the calculator check the arithmetic.	Ask a word problem beside the wheel, or just type the sentence
Explain	Walks through the working for an answer the calculator already found.	The Explain button on any answer

Each of these uses 1 AI credit. You get free AI credits every day without signing up, the bar above the solver shows how many are left, and paid plans include more. If the AI cannot read or solve what you sent, the credit comes back.

When you type a problem

You do not have to choose a mode. The solver works out whether the line is a sum, an equation, a function to graph, a matrix, a list of data or a unit conversion. The answer lands on a tape as a card with buttons to graph it, take its derivative or integral, factor it or copy it. ans is the last result, you can name values such as r = 4.5 and use them in later lines, and clicking an earlier line lets you fix it. Find a solver on the wheel brings the wheel back.

What you can type

You type	You get
`3/8 + 5/12`	19/24, with the decimal
`sqrt(8) + sin(60)`	The decimal and the exact value
`x^2 - 5x + 6 = 0`	x = 2 and x = 3, with steps
`2x + 3y = 12, x - y = 1`	The solution of the system
`2x - 3 < 7`	The range of x that works
`derivative of x^2 sin(x)`	The derivative, rule by rule
`integrate x^2 from 0 to 3`	9
`limit of sin(x)/x as x->0`	1
`factor x^3 - 8`, `expand (x+2)^3`	The rewritten expression
`[[2,1],[5,3]]^-1`	The inverse matrix, plus determinant, transpose and row reduction
`4, 8, 15, 16, 23, 42`	Mean, median, quartiles and standard deviation
`5 ft 7 in to cm`, `60 mi/h to m/s`	The converted value
`0xFF + 0b1010`	265, also in hex, binary and octal
`15% of 240`, `2^100`, `52!`	Percentages and very large whole numbers in full
`(3 + 4i)(1 - 2i)`	11 − 2i, with the polar form
`f(x) = x^2 + 1` then `f(3)`	Your own functions

Graphing in 2D and 3D

Any expression with x in it can be graphed with one tap. On the Graph tab, which you can also reach from the panel beside the wheel, you can add several lines, drag to move, pinch or scroll to zoom, and tap a curve to read a point. Zeros, turning points and crossings are marked for you. Letters that are not x or y, such as the a and b in a sin(b x), become sliders you can drag or animate.

The 3D tab draws surfaces such as z = sin(x) cos(y), closed shapes such as x^2 + y^2 + z^2 = 16, space curves such as (3 cos(t), 3 sin(t), t/3), and spherical plots written with rho. Drag to turn the figure and scroll to zoom.

Good to know

The wheel without a mouse. Click the wheel, then use the arrow keys to turn it, Enter to go in and Esc to go back.
Recent solvers. The solvers you opened last are listed beside the wheel, so the one you use every week is one tap away.
A plain list. Browse every solver as a list under the wheel shows the same solvers as ordinary links.
Sound. The wheel is silent until you turn on Sound.
Angles. The solver starts in degrees. The DEG / RAD button switches. Graphs always use radians.
Logarithms. log is base 10, ln is natural, and log(x, b) is base b.
Second functions. Hold a key for the small symbol in its corner.
Floating window. In Chrome and Edge, the window button keeps the calculator on top of your other apps.
Where the work happens. Arithmetic and graphs are worked out on your device. Equations and calculus are sent to our server to be solved and are not stored. Photos are sent to an AI service to be read.

Frequently asked questions

How do I find the right solver?

Pick a topic on the wheel, then pick what you want to do. The wheel then shows the solvers for that job, and the panel beside it says what each one does. You can also type part of a name, such as percent or triangle, and press Enter to open the first match.

How many math solvers are on the wheel?

More than 450, which is every math solver on MiniWebtool. They are sorted into twelve topics, from everyday numbers and fractions to calculus, statistics and matrices. The same set is also under the wheel as a plain list.

What does SPIN do?

SPIN lands on a solver at random and shows what it does. Nothing opens until you press Open solver, so you can keep spinning.

Is this an AI math solver?

Partly, on purpose. A problem you type is worked out by a calculator and an algebra engine, which do not make arithmetic slips. AI is used where it helps: reading a problem from a photo, setting up a word problem and explaining an answer in plain language. Everything that uses AI is marked AI and shows its cost.

Is the Math Solver free?

Yes. The wheel, calculations, graphs, 3D plots, equation solving and the steps the solver works out by rule are free with no sign-up. The three AI features, photo, word problems and Explain, use 1 AI credit each: everyone gets free AI credits every day, and paid plans include more.

Does it show the steps?

Yes. Linear and quadratic equations, derivatives and many integrals come with steps that name the rule used at each stage. For anything else, the Explain button asks AI to walk through the working for the answer the calculator already found.

Can I solve a math problem from a photo?

Yes. Tap Photo, the button marked AI, to take or upload a picture, or paste a screenshot. AI reads the problem into the input line so you can check it, and then the calculator solves it. The answer comes from the calculator, not from a guess.

Is log base 10 or natural log?

log(x) is base 10 and ln(x) is the natural logarithm, the same as on a scientific calculator. For another base write log(x, 2).

Why does sin(30) give 0.5?

The solver starts in degrees, so sin(30) is 0.5. Click DEG to switch to radians, where sin(pi/6) is 0.5. The setting is remembered.

What can I graph?

In 2D: functions such as y = x^2 - 4, curves such as x^2 + y^2 = 25, inequalities, polar curves such as r = 1 + cos(theta) and parametric curves. Letters other than x and y become sliders. In 3D: surfaces such as z = x^2 - y^2, shapes such as x^2 + y^2 + z^2 = 16, space curves, and spherical and cylindrical plots.

Can I use it as a scientific calculator?

Yes. Tap Calculator beside the wheel, or just work out a first problem, and the keypad appears. It has trigonometry, logarithms, powers, roots, factorials, combinations, constants and units. Hold a key to get its second function, for example hold sin for inverse sine.

Are my calculations saved?

Your tape is kept in this browser so it is still there when you come back: tap Your answers beside the wheel. Clear removes it. Share copies a link that opens the same lines on another device.
