Expressions and Equations Calculators

Samuel Dominic Chukwuemeka I greet you this day,
Please solve the questions on your own before checking your answers with the calculators.
I wrote the codes for some of the calculators using JavaScript, a client-side scripting language.
The Wolfram Alpha widgets (many thanks to the developers) were used for some calculators.
Comments, ideas, areas of improvement, questions, and constructive criticisms are welcome. You may contact me.
If you are my student, please do not contact me here. Contact me via the school's system.
Thank you for visiting!!!

To see the answer(s) in decimals, click the "Approximate forms" link.
To see the answer(s) in the simplest / exact forms, click the "Exact forms" link.

To use the calculator, please:
(1.) Type your equation in the textbox (the bigger textbox).
(2.) Type it according to the examples I listed.
(3.) Delete the "default" expression in the textbox of the calculator.
(4.) Copy and paste the equation you typed, into the small textbox of the calculator.
(5.) Click the "Submit" button.
(6.) Check to make sure that it is the correct equation you typed.
(7.) Review the answers.

  • Using the Solve Equations Calculator
  • All outputs/answers are written as both integers and/or decimals; and integers and/or fractions.
  • Linear Equations: Type: $5p - 4 = 21$ as 5 * p - 4 = 21
  • Linear Equations: Type: $-1.2p + 1.25 = 0.77$ as -1.2 * p + 1.25 = 0.77
  • Linear Equations: Type: $\dfrac{3}{10} - \dfrac{7k}{15} = \dfrac{2}{3}$ as (3/10) - (7 * k/15) = (2/3)
  • Linear Equations: Type: $-2m - 3(4 - 2m) = 2(m - 3) + 2$ as -2 * m - 3 * (4 - 2m) = 2 * (m - 3) + 2
  • Linear Equations: Type: $2[-(x - 1) + 4] = 5 + [-(6x - 7) + 9x]$ as 2 * [-(x - 1) + 4] = 5 + [-(6 * x - 7) + 9 * x]
  • Linear Equations: Type: $2x - {x - [3x - (6x + 9)]} = 8x - 1$ as 2 * x - {x - [3 * x - (6 * x + 9)]} = 8 * x - 1
  • Rational Equations: Type: $\dfrac{4}{p + 8} + \dfrac{5}{p^2 - 8p + 64} = \dfrac{768}{p^3 + 512}$ as (4/(p + 8)) + (5/(p^2 - 8 * p + 64)) = (768 / (p^3 + 512))

Solve Literal Equations - Solve for a Specified Variable

This calculator will:
(1.) Solve any equation for a specified variable.
In other words, it expresses a variable in terms of other variables.

To use the calculator, please:
(1.) Type your equation in the textbox (the bigger textbox).
(2.) Type it according to the examples I listed.
(3.) Delete the "default" equation in the textbox of the calculator.
(4.) Copy and paste the equation you typed, into the small textbox of the calculator.
(5.) Type the variable for which you want to isolate.
(5.) Click the "Submit" button.
(6.) Check to make sure that it is the correct equation you typed.
(7.) Review the answer.

  • Using the Solve Literal Equations Calculator
  • Type: $V = l * w * h$ for $w$ as V = l * w * h for w
  • Type: $F = \dfrac{mv}{t}$ for $t$ as F = (m * v)/t for t
  • Type: $P = a + b + c$ for $b$ as P = a + b + c for b
  • Type: $A = \dfrac{1}{2}h(l_1 + l_2)$ for $h$ as A = (1/2) * h * (l_1 + l_2) for h
