Calculators

Arithmetic Calculator with procedure This calculator shows you not only results but also shows you the procedure, you can do: MEGA ADDITIONS, MEGA SUBSTRACTIONS, MEGA MULTIPLICATIONS and MEGA DIVISIONS You can do arithmetic of natural numbers unusually big!	Square Root Calculator with procedure Calculate the value of the square root of a positive integer, so you can say you can do with a common calculator, but this program brings you the partial results of the square root the algorithm, the procedure.
Equivalents Electrical Resistors Calculator Calculates the equivalent electrical resistor you need with a maximum of three resistors using real resistor values, so you just write the value of the resistor you need, and this page will guive you the electric diagram with real resistor values.	Resistor Color Codes Calculator Select the colors and you receive the resistor's value, for resistors used in electronics. Parallel Resistors Calculator This program calculates the equivalent electrical resistor of n resistors wired in parallel.
Descriptive Statistics Calculator Calculate the values of descriptive statistics, mean, mode, median, number of data, minimum, maximum, sample standard deviation, population standard deviation sample variance, population variance and frequency table..	Calculation of the area and coordinates of a terrain by the polygon method Calculate the area of a terrain using the polygon method. It also allows us to find the coordinates so we can draw a sketch of it..
Two linear equations Calculator Calculates the two possible results for a system of linear equations with two variables.	.Greatest Common Factor and Least Common Multiple Calculator Calculates the least common multiple (LCM) and the Greatest Common Factor (GCF) for a set of natural numbers. If the numbers are not to large, and there are not many numbers, you will see the procedure.
Numerical Base Conversion Calculator Numerical Base Conversion Calculator for positive integers from base 2 (binary) to base 20 through base ten and base 16 (hexadecimal), put the base and the number in that base, and you will get the same number in the remaining 19 bases . For base twenty: A = 10, B = 11, C = 12, D = 13, E = 14, F = 15, G = 16, M = 17, I = 18 J = 19.	Frequency Counting and Percentages Calculator This page count the frequencies of the values of a set of data and calculates their percentage. Raffle online Allows you to make raffles, selecting data or numbers randomly, is very useful for research models.
Quadratic Equation Calculator with Procedure This page find the roots of a quadratic equation by the formula and shows you the procedure. Also tells you if the roots are reals and differents, is a double root, are complex conjugate or imaginary roots.
