With the Time Calculator you can calculate the subtraction between 2 dates:
You can fix a date in the past and subtract it from the present time: You get the elapsed time.
You can fix a date in the future and subtract the present time: You get the countdown to the fixed date.
(Light gray dates are in the past; Light green dates are in the future)
Don't work for dates earlier than 1582.
(Because the Gregorian Calendar)

This easy to use calculator will help you solve a wide range of linear equations with one unknown, including linear equations involving parentheses, fractions, and decimals.
The virtual keyboard allows you to easily input a linear equation just as it is written on paper.
For solving linear equations in the form ax + b = с and ax + b = cx + d you can use special templates.
The equation solver DOES NOT SOLVE fractional equations with a variable in the denominator.
Requirements: Adobe AIR.
System of equations:
-2x+3y+5 = 0

Enter an inequality that is <, <=, >, >= or = and this works out the solution for you. It basically does just what it says on the tin. So if you have homework that you need to check the answers for, then look no further.
This tool is taken from the selection of tools that appears on my live worksheet app on Inequalities and the Modulus Function, that appears on my wolfram alpha developer page.
Hope it proves helpful.
It supports factoring non-monic equations (A > 1) and is ABSOLUTELY FREE!
Also i'd appreciate it if you rated this app.
If you find an error in the calculations, PLEASE email me the equation and i will have a look at it. Thanks
P.S This program is open source
All step by step, like a real teacher, showing all steps necessary to achieve the result.
Use it as a tutor to help you to learn mathematics.
Please, use solver responsibly
