A better calculator in every way.
A better view of your calculation.
More intuitive to enter and edit.
Easier for everyday use.
More capable for advanced problems.
Seeing is everything:
Your calculation is beautifully and mathematically formatted.
Everything is easier to understand.
You see the whole expression. You are less likely to make mistakes.
To see it bigger, just resize the window.
You also have extensive viewing options.
Enter naturally and quickly:
Enter the way you see it.
For example: 2 sin 9 + 3
On a typical calculator, you enter: 2 x 9 sin + 3
On others, you enter: 2 * sin(9) + 3
On Magic Number: 2 sin 9 + 3
Lots of easy and convenient shortcuts.
Yes, you can press X to multiply.
Edit without thinking:
Its faster and easier than any editor!
Made a mistake? Just click and type over it.
You can navigate with just the left or right arrow keys.
You can work with any type of numbers:
fractions, percentages, and even complex numbers.

What's New in Version 2.1
New features include:
A new and easy way to do compound interest related calculations.
(See: Help > Percentages)
For trigonometry fans, you get cosecant (csc), secant (sec), cotangent (cot).
You get the hyperbolic counterparts too: csch, sech, coth.
Adjacent function to calculate the other right-angled side of a triangle.
K is not just for 1000. You can use it like a variable.
Option to automatically insert closing bracket / parenthesis.
Option to use tau, where ? = 2?, to make radians more intuitive.
Fixed the issue with duplicate expressions in history.
Planck Temperature now has the correct value.
0^-1 now returns as undefined instead of 0.
Fixed a rare bug that the result is formatted as 0.
