Pito Salas is considered as the "father of pivot tables" according to the book "Pivot Table Data Crunching" written by Bill Jelen and Mike Alexander. Salas discovered that spreadsheets contained data patterns that could aid in data processing. He built on this concept and later developed Lotus Improv, which became the precursor for pivot tables.

To square a number, multiply it by itself. Five squared is 5 times 5, which equals 25. A number cubed is multiplied by itself twice: 5 times 5 times 5 is 5 cubed, which equals 125. The terms "squared" and "cubed" come from the formulas for calculating the area of a square and the volume of a cube. The area of a square is the length of its sides squared; the volume of a cube is the length of its sides cubed.

In the above formulas, "h" is the value of "x" at the center of the hyperbola, while "k" is the value for "y" at the center of the hyperbola. The value of "a" is the distance from the vertex of the hyperbola to its center. The value for "b" is the height of the fundamental box defined by the hyperbola.

Converting fractions to decimals is not as problematic as it may sound. It involves simple division. One simply needs to divide the denominator, or the number on the bottom of the fraction, into the numerator, which is the number on the top. The resulting decimal is the answer equivalent to the original fraction.Using the fraction 1/6 as an example, there are just a few steps to find the decimal.The first step is to divide 6 into 1. Since 1 is less than 6, one needs to add a few decimal places after the number, making it 1.0000.Divide 6 into 1.0, which works out to 1 with a remainder of 4.Brin..

The word perimeter comes from the Greek word "peri," which means "around," and the Greek word "meter," which means "measure." The perimeter can also be easily defined as the outline of an object. The perimeter is important in a variety of applications, including finding out how much fence is needed for a yard or pasture. The perimeter can also be used to describe how far a wheel will roll in one revolution.

Even if the position of the numbers is swapped around, the answer remains the same. Individual numbers that are added are known as addends. The symbol of addition has been used for centuries, but it was only in the 16th century that the symbol was made universal. Until then, mathematical equations were written in words. Addition is sometimes referred to as sum, plus, increase and total.

Numbers one through 10 in Roman numerals are expressed as follows: I, II, III, IV, V, VI, VII, VIII, IX, X. One, two and three are simply one two and three lines. Four is represented essentially as one less than five, IV. V is five, six is five plus one, or VI, and so on. Nine is 10 minus one, or IX. This pattern continues all the way to 3,999. To break down a larger number, use the current year - 2015. Two thousand is expressed with two of the thousand symbol, MM. Fifteen is ten plus five or XV. So the year 2015 in Roman numerals is MMXV.\nSmaller number symbols almost always go to the right ..

A mathematical equation is a statement that asserts that two different expressions are equal. The expressions are usually separated by an equals sign to show that one side balances the other.\nA chemical equation is a formula for showing a chemical reaction. It displays the type and the amount of starting materials and the results that are produced when they react. The inputs must equal the outputs, as nothing in the reaction is wasted.

The equation used to find the range of a data set is "maximum value - minimum value = range." To find the range of the data set given as "5, 7, 9, 1, 11, 4, 8, 5 and 12," one finds the minimum value of the data set as 1. The maximum value is 12. By subtracting these two values, the range is 11, or "12 - 1 = 11."\nTo find the maximum and minimum values of a data set that contains many values, order the values in the set from lowest to greatest.
