Trisomy disorders The addition of an extra chromosome usually occurs spontaneously during conception. The cause of this is unknown and prevention is not possible. The most important risk factor for trisomy disorders is maternal age. Women in their late 30s and 40s are more likely to have babies with trisomy than younger women. Trisomy 21 - Down syndrome

What is the difference between arithmetic and geometric averages? By Chris Gallant AAA |. A: An arithmetic average is the sum of a series of numbers divided by the count of that series of numbers. If you were asked to find the class (arithmetic) average of test scores, you would simply add up all the test scores of the students, and then divide that sum by the number of students.

Modular arithmetic Modular arithmetic. Time-keeping on a clock gives an example of modular arithmetic. Modular arithmetic, sometimes also called clock arithmetic, is a way of doing arithmetic with integers. Much like hours on a clock, which repeat every twelve hours, once the numbers reach a certain value, called the modulus, they go back to zero. People talked about modular arithmetic in many ancient cultures.

Arithmetic Mean (Average) - GMAT Math Study Guide 1 More Complex Examples.  Mean (aka Arithmetic Mean, Average) - The sum of all of the numbers in a list divided by the number of items in that list. For example, the mean of the numbers 2, 3, 7 is 4 since 2+3+7 = 12 and 12 divided by 3 [there are three numbers] is 4.

What is the 'Arithmetic Mean' What is the 'Arithmetic Mean' The arithmetic mean is a mathematical representation of the typical value of a series of numbers, computed as the sum of all the numbers in the series divided by the count of all numbers in the series. The arithmetic mean is sometimes referred to as the average or simply as the mean. Some mathematicians and scientists prefer to use the term arithmetic mean to distinguish it from other measures of averaging, such as the geometric mean and the harmonic mean.

mean The arithmetic mean is a value that is derived by dividing the total of a set of values by the number of items in the set. The geometric mean is a value between the first and last of a set of values organized in a geometric progression.

- Algebra (from Arabic al-jabr meaning reunion of broken parts) is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.

Algebra Algebra is a part of mathematics (often called math in the United States and maths in the United Kingdom ). It uses variables to represent a value that is not yet known. When an equals sign (=) is used, this is called an equation.

arithmetic mean arithmetic mean. (ār'ĭth-mět'ĭk) The value obtained by dividing the sum of a set of quantities by the number of quantities in the set. For example, if there are three test scores 70, 83, and 90, the arithmetic mean of the scores is their sum (243) divided by the number of scores (3), or 81. See more at mean.

Glossary - Mathematical words you need to know Algebra is the branch of mathematics where symbols or letters are used to represent numbers. Angle. An angle is formed when two straight lines cross or meet each other at a point. The size of an angle is measured by the amount one line has been turned in relation to the other. Approximate. An approximate value is a value that is close to the actual value of a number.

equation in mathematics, a statement, usually written in symbols, that states the equality of two quantities or algebraic expressions, e.g., x+3=5. The quantity x+3, to the left of the equals sign (=), is called the left-hand, or first, member of the equation, that to the right (5) the right-hand, or second, member. A numerical equation is one containing only numbers, e.g., 2+3=5.

Algebra Algebra is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. As such, it includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields. The more basic parts of algebra are called elementary algebra; the more abstract parts are called abstract algebra or modern algebra. Elementary algebra is generally considered to be essential for any study of mathematics, science, or engineering, as well as such applications as medicine and economics.

arithmetic mean The arithmetic mean of a continuous function over a defined interval is determined by first calculating the definite integral over the interval, and then dividing this quantity by the width of the interval. Also see Mathematical Symbols.
