The abacus is a basic mathematical computing device. It is still widely used today in Africa, Japan, Russia, China and other countries as a visual aid to facilitate the learning of mathematical concepts.
A:A real world example of an absolute value function is any calculation in which the total depends upon simple addition of all the quantities in the function, regardless of sign. One example of such a calculation is the number of feet traveled by an athlete running around a race track.
A:When purifying a substance in chemistry, use (collected mass/starting mass)*100 to calculate percent recovery. This formula is also commonly stated as (pure product recovered/crude material used)*100.
A:The common formula to find the area of an isosceles triangle is area equals 1/2 * base * height of triangle. The height is the line bisecting the two equal sides of the triangle and intersects the midpoint of the base.
A:The word "term" is used in mathematical equations to describe either a single number, or numbers and variables multiplied together. Numerical terms are then grouped into expressions to come up with a definitive answer to the equation.
A:To calculate the mass of a specific number of atoms of an element, divide the number of atoms by 6.02 x 1023 and then multiply by the molar mass of the element. The process for calculating mass from the number of atoms is the same for all elements.
A:Changing square feet to square meters requires use of basic conversion where one square meter equals 10.76 square feet. Hence, one square foot equals approximately 0.093 square meters. A house that has 2,500 square feet is 232.5 square meters in size.
A:The abacus is a basic mathematical computing device. It is still widely used today in Africa, Japan, Russia, China and other countries as a visual aid to facilitate the learning of mathematical concepts.
A:Two early counting devices were the abacus and the Antikythera mechanism. The abacus and similar counting devices were in use across many nations and cultures. The Antikythera mechanism hails from the Greek island of Antikythera.
A:The formula to convert kilograms to pounds is pound = kilogram/0.45359237. Conversely, the formula is kilogram = pound x 0.45359237. One kilogram is equal to roughly 2.2 pounds, and 1 pound is roughly 454 grams.
A:Qualitative analysis is the scientific study of data that can be observed, but not measured. It is concerned with cataloguing the qualities of what is studied. Quantitative analysis is the study of data that can be measured, the quantities of a category of data. Each type of inquiry contributes important insights to scientific study that the other cannot.
A:There are many kinds of calculators, but most calculators have the same standard keys that allow users to complete a variety of calculations. The number keys and addition, subtraction, multiplication, division and equal signs are all very straightforward, but the functions of the other keys are not so well-known.
A:Some popular online math calculators are MathWay.com, WolphramAlpha.com and Calculator.net. Each of these include tools to help you solve problems in basic math, algebra, geometry, trigonometry, calculus and even chemistry.
A:A square root solver or calculator is a tool that helps one compute the square root of any number. There is a square root solver at Math.com as of 2014, and there is also a square root solver on most calculators. To use a square root calculator, one simply needs to enter a number and hit the square root sign (?). Then, the answer is generated.
A:To use a square footage calculator to measure a room, first find its length and width measurements, either in feet or feet and inches. Input the measurements into the corresponding boxes of the calculator, and then hit Calculate. For example, using the calculator on Green Home Solutions' website, ghsproducts.com, a room 10 feet wide and 120 feet long has an area of 120 square feet.
A:The multiples of 24 are an infinite series of numbers that result from 24 being multiplied by any whole number. The first five multiples of 24 are 24, 48, 72, 96 and 120. These numbers come as a result of 24 being multiplied by 1, 2, 3, 4 and 5.
A:There are approximately 15 to 17 cc per horsepower, so 600 cc is equal to 35 to 40 horsepower. There are too many variables to enable an exact conversion, so the number of horsepower to 600 cc can only be estimated.
A:Financial calculators make excellent tools for planning, forecasting and preparing a wide variety of financial decisions. They simplify several calculations, such as compound interest and regular payments, and can provide graphs that plot assets over time depending on a number of variables that the user can change and compare.
A:A piecewise function grapher is an application that produces graphs for given piecewise functions. The calculator TI-83/84 has the piecewise function-graphing feature, which is used in DOT mode to avoid connecting two pieces that should not be connected.
A:Think Through Math offers a number of activities designed to motivate students in grades 3 and above to want to learn math, including games and theme-based contests. Students also have the ability to earn points that they can use to customize avatars and program dashboards or donate to charities.
A:Some good math calculators are the TI-Nspire CX Cas, TI-84 Plus C Silver Edition, Casio Prizm, HP Prime and TI-89 Titanium. These calculators are capable of handling basic arithmetic, complex scientific formulas and graphing.
A:Texas Instruments, Hewlett Packard, Casio and Sharp all sell basic scientific calculators at reasonable prices. All are available for purchase from Amazon.com, Staples and Best Buy, as of 2015.
