<h1>Online calculator reduces human efforts</h1><strong> Author: <a href='http://www.articleseen.com/profile_mahan.aspx'>mahan</a></strong><br /><p><p>This article will tell about different online calculators and how these online calculators help us in solving our mathematics problem. Today I am going to discuss about three different calculators used in mathematics that are Scientific Notation Calculator , Probability Calculator and Square footage calculator. Firstly I am going to discuss about Square footage calculator. Before proceeding further, we need to know about the meaning of square foot. A square foot is a unit of area measurement equal to a square measuring one foot on each side. 1 Square Foot = 0.0929 square meters. Calculating the square footage, it refers computing the area by foot. The Square Footage Calculator is a tool for calculating the square footage of a room. The formula to calculate square footage is simply length times height. Let’s take an example to understand it better. To find the square footage of a rectangle, square, or anything with four sides, we just need to multiply the length and the width. Let's see an example to understand it better:</p> <p>Length (L) = 4 feet Width (W) = 7 feet. Square Footage = Length x Width = 4 ft x 7 ft Square Footage of rectangle is = 28 square feet (sq ft). </p> <p>Now let’s talk about probability calculator. Probability is basically a way of telling or expressing knowledge that an event will occur or has occurred. It can be written as: P(B|A) = P(A and B) / P(A) P(A/B) = Probability of occurrence of event A when the event B has already occurred and P(B/A) = Probability of occurrence of event B when the event A has already occurred. </p> <p>A simple way of getting a probability is by using a probability calculator. First question comes in our mind is that what is a probability calculator? The Probability Calculator calculates the probability of an event, based on probabilities of other related events, that has already occurred. Probability calculator also helps in solving conditional probabilities.</p> <p>Now I am going to discuss about Scientific Notation calculator. A number in scientific notation is written as the product of a number (integer or decimal) and a power of 10. This number is always 1 or more than one and less than 10. Scientific Notation is based on powers of the base number 10. The number 23,000,000,00 in scientific notation is written as :2.3 x 1010 </p> <p>Scientific Notation Calculator helps to solve our large and small problems in a faster and better manner. Let's see how scientific notation calculator works: </p> <p>Punch the number (the digit number) into your calculator. Push the EE or EXP button. Do NOT use the x (times) button!!</p> <p>Enter the exponent number. Use the +/- button to change its sign. Finally, treat this number normally in all subsequent calculations.</p> </p><strong>About the Author:</strong><br /><p>TutorVista is the #1 portal for learning <a rel="nofollow" href="http://calculator.tutorvista.com/math/456/probability-calculator.html" title="Probability Calculator">Probability Calculator</a>.
