This tool lets you converter roman numerals to traditional numbers, and traditional numbers to roman numerals. A smaller number in front of a larger number means subtraction, all else means addition. For example, IV means 4, VI means 6.You would not put more than one smaller number in front of a larger number to subtract. For example, IIV would not mean 3.

Quadratic equation has the form ax2 + bx + c = 0. It will generally have two solutions; that is, two different values of x that make the equation true. It can happen that both solutions are the same number, and it is possible that the solutions will be complex or imaginary numbers. To use this software, type in values for a, b, and c in the boxes below, and press the Solve for X button.

It is not difficult to learn how to calculate the percentage of one number vs. another number. All you have to do is divide one number by another number.
