Math problem solver

Type an equation or expression. Get the answer and every step.

What you can type

Use the keys for fractions, powers and roots, or type them: ^ for powers, / for fractions, sqrt( ) for roots. For anything else, like systems of equations, triangles or statistics, pick a calculator.

Worked examples

Solve 3(x + 2) = 12

x = 2

Steps

  1. Start with 3x + 6 = 12.
  2. Subtract 6 from both sides: 3x = 6.
  3. Divide both sides by 3: x = 6 รท 3 = 2.
  4. Check: left side 12, right side 12.

Add 3/4 + 5/6

34 + 56 = 1912

Mixed number
1 7/12
Decimal
โ‰ˆ 1.583333

Steps

  1. Common denominator 12: 9/12 + 10/12 = 19/12

Simplify โˆš180

โˆš180 = 6โˆš5

Decimal
13.416408

Steps

  1. Largest perfect square that divides 180: 36, because 180 = 36 ร— 5.
  2. โˆš180 = โˆš36 ร— โˆš5.
  3. โˆš36 = 6, so โˆš180 = 6โˆš5.

How the solver works

The solver reads what you type, picks the calculator that fits and fills it in for you. Every answer comes from fixed math rules, the same ones on each calculator page, so the same problem always gets the same answer and steps. If it can’t solve a problem yet, it says so and points you to the calculators.
