Math homework helper: every problem, every step

This math homework helper solves your homework problems step by step, from algebra and geometry to calculus and statistics. Type a problem, scan it, or choose a photo of the worksheet. HexMath shows numbered steps and a boxed final answer, and you can ask a follow-up question about any step you do not understand.

What this page covers

  • Homework problems in arithmetic, algebra, geometry, trigonometry, calculus, statistics and linear algebra.
  • Word problems, typed or scanned.
  • A whole worksheet from one photo, solved as a list.
  • Not covered here: subjects other than math. For one photographed problem, see the photo math solver.

How to enter the problem

  • Type it or paste it. For a word problem, include the question it asks.
  • 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.

Worked examples

Example 1: A phone plan costs 20 dollars a month plus 0.10 dollars per text. This month's bill is 27.50 dollars. How many texts were sent?

Problem

A phone plan costs 20 dollars a month plus 0.10 dollars per text. This month's bill is 27.50 dollars. How many texts were sent?

Answer

Verified

The answer is

7575 texts

Explanation

  1. Name the unknown
    Let tt be the number of texts.
  2. Write the equation
    Fixed cost plus cost per text equals the bill
    20+0.10t=27.5020 + 0.10t = 27.50
  3. Isolate the term with t
    Subtract 2020 from both sides
    0.10t=7.500.10t = 7.50
  4. Solve
    Divide by 0.100.10
    t=75t = 75

Example 2: A right triangle has legs of 9 cm and 12 cm. How long is the hypotenuse?

Problem

A right triangle has legs of 9\displaystyle 9 cm and 12\displaystyle 12 cm. How long is the hypotenuse?

Answer

Verified

The answer is

1515 cm

Explanation

  1. Use the Pythagorean theorem
    c2=a2+b2=92+122=81+144=225c^2 = a^2 + b^2 = 9^2 + 12^2 = 81 + 144 = 225
  2. Take the square root
    c=225=15c = \sqrt{225} = 15

Example 3: Find the mean of the test scores 78, 85, 92, 88, 77.

Problem

Find the mean of the test scores 78,85,92,88,77\displaystyle 78, 85, 92, 88, 77.

Answer

Verified

The answer is

8484

Explanation

  1. Add the scores
    78+85+92+88+77=42078 + 85 + 92 + 88 + 77 = 420
  2. Divide by the number of scores
    There are 55 scores, so the mean is 4205=84\frac{420}{5} = 84.

Common mistakes

  • Typing a word problem without the question it asks. The solver needs to know what to find.
  • Leaving out a condition or unit, such as x > 0 or centimetres.
  • Entering several problems on one line. Enter one at a time, or scan the worksheet.
  • Copying the final answer without the working. Most teachers grade the steps.

Checks, assumptions and limits

  • Check the problem at the top of the solution against your homework before reading the steps.
  • Check the answer against the question. In the first worked example, 20 + 0.10 × 75 = 27.50, the bill.
  • HexMath can make mistakes. Double check important steps.

Frequently asked questions

Copying answers you cannot reproduce works against you on the test. Reading the steps, asking about the one you do not understand, then solving the next problem yourself is studying.

Yes. Type the whole problem, including the question, or scan it. Check how the words were turned into an equation before reading the rest of the steps.

No. HexMath is built for math only, from arithmetic to calculus, statistics and linear algebra.
