Free AI math tutor: ask about any step

This free AI math tutor explains a math problem step by step and answers your questions about any step. Type a problem, scan it, or choose a photo. HexMath shows numbered steps and a boxed final answer, and when a step is unclear you ask a follow-up question in the same thread, as you would ask a tutor.

What this page covers

  • Step-by-step solutions in arithmetic, algebra, geometry, trigonometry, calculus, statistics and linear algebra.
  • Follow-up questions about any step, answered in the same thread.
  • Typed, scanned or photographed problems.
  • Not covered here: lesson plans or a course schedule. For a quick answer to homework, see the math homework helper.

How to enter the problem

  • Type it or paste it.
  • Scan it. Fit the one problem in the frame.
  • Choose a photo. Several problems in one photo are solved as a list.
  • Then tap Solve, and ask a follow-up about any step.

Worked examples

Example 1: Solve x² - 5x + 6 = 0.

Problem

Solve x2−5x+6=0\displaystyle x^2 - 5x + 6 = 0.

Answer

The answer is

x=2x = 2 or x=3x = 3

Explanation

  1. Factor the quadratic
    Find two numbers that multiply to 66 and add to −5-5: −2-2 and −3-3. So x2−5x+6=(x−2)(x−3)x^2 - 5x + 6 = (x - 2)(x - 3).
  2. Set each factor to zero
    x−2=0x - 2 = 0 or x−3=0x - 3 = 0.
  3. A follow-up you could ask: why set each factor to zero?
    If a product of two numbers is 00, at least one of them must be 00. So (x−2)(x−3)=0(x - 2)(x - 3) = 0 only when x−2=0x - 2 = 0 or x−3=0x - 3 = 0.

Example 2: Simplify (2x³)(3x⁴).

Problem

Simplify (2x3)(3x4)\displaystyle (2x^3)(3x^4).

Answer

The answer is

6x76x^7

Explanation

  1. Multiply the numbers
    2⋅3=62 \cdot 3 = 6
  2. Multiply the powers of x
    x3⋅x4=x3+4=x7x^3 \cdot x^4 = x^{3+4} = x^7
  3. A follow-up you could ask: why add the exponents?
    x3x^3 is three factors of xx and x4x^4 is four more, so together there are seven factors of xx.

Example 3: What percent of 120 is 30?

Problem

What percent of 120\displaystyle 120 is 30\displaystyle 30?

Answer

Verified

The answer is

25%25\%

Explanation

  1. Write the fraction
    The part over the whole is 30120=14\frac{30}{120} = \frac{1}{4}.
  2. Convert to a percent
    14=0.25=25%\frac{1}{4} = 0.25 = 25\%
  3. A follow-up you could ask: how can I check it?
    Take 25%25\% of 120120: 0.25⋅120=300.25 \cdot 120 = 30. It matches.

Common mistakes

  • Reading only the final answer. The steps are where the method is.
  • Asking a follow-up about the whole solution. Name the step you do not follow, such as step 2.
  • Moving on before you can redo the problem without looking. Try a similar one yourself.
  • Entering several problems on one line. Enter one at a time, or scan the worksheet.

Checks, assumptions and limits

  • Check the problem at the top of the solution against your page before reading the steps.
  • Check the answer by substitution where you can. In the first worked example, 2 squared minus 5 times 2 plus 6 is 0, and so is 3 squared minus 5 times 3 plus 6.
  • HexMath can make mistakes. Double check important steps.

Frequently asked questions
