Definitions for **"Scientific notation"**

A system in which a number is expressed as a number between 1 and 10, times 10 raised to an exponent.

representation of a number as the product of a number between 1 and 10 and a power of 10; used especially for very small or very large numbers - examples: 6,900,000 = 6.9 X 10^ or .00069 = 6.9 X 10

numerical short-hand which uses powers of ten as a simplified way of expressing numerical values (numbers are written with one digit to the left of the decimal times a power of ten)

Scientific notation provides a convenient way of writing very large and very small numbers. For example, 2.2 x 104 is equivalent to 22,000, and 5.1 x 10-6 is the same as 0.0000051.

the representation of a quantity as a decimal number between one and ten multiplied by ten raised to a power

see standard exponential notation

writing a number as the product of a number between 1 and 10 and the appropriate power of ten. e.g. 118 000 = 1.18 X 105.

A shorthand method used by all types of scientists for writing especially large or small numbers. Scientific notation consists of two parts: a real number between 1 and 10 and the number 10 raised to a certain power. When these two numbers are multiplied together, the product is the number being represented. For example, the number 694 can be written in scientific notation as 6.94 x 10^2, which is 6.94 x 100, or 694. As another example, the number 0.003 can be written in scientific notation as 3 x 10^-3, which is 3 x 0.001, or 0.003. Scientific notation is especially useful to astronomers because they deal with extremely large and extremely small numbers. It is much easier for an astronomer to write the mass of the Sun as 1.99 x 10^33 grams rather than 1990000000000000000000000000000000 grams, or the mass of an electron as 9.1 x 10^-28 grams, rather than 0.00000000000000000000000000091 grams.

A short-hand way of writing very large or very small numbers. The notation consists of a decimal number between 1 and 10 multiplied by an integral power of 10. For example, 47,300 = 4.73 x 4; 0.000000021 = 2.1 x 10 -8

A method for writing extremely large or small numbers compactly in which the number is shown as the product of two factors.

(4) A system for representing numbers in which a number is written as the product of a power of 10 and a number that is at least 1 but less than 10. Scientific notation allows writing big and small numbers with only a few symbols. Example: 4,000,000 in scientific notation is 4 x 106. 0.00001 in scientific notation is 1 x 10-6

Displaying a number in this formula: N * 10^x. Where N=a number greater than 1 but less than 10. X=an exponent of 10. Example: 727900 in scientific notation is: 7.279 * 10^5

a way of expressing a number as the product of a power of ten and a number between 1 and 10

A compact format for writing very large or very small numbers, most often used in scientific fields. The notation separates a number into two parts: a decimal fraction between 1 and 10, and a power of ten. Thus 1.23 x 104 means 1.23 times 10 to the fourth power or 12,300; 5.67 x 10-8 means 5.67 divided by 10 to the eighth power or 0.0000000567.

A convenient way of writing very large or very small numbers. 2x1027 means 2 followed by 27 zeros. (The 27 should be a superscript; some web browsers don't get it right). Basically the decimal point is moved 27 places to the right, filling in any spaces with zeros. So 1.6x10 27 means 16 followed by 26 zeros. 2x10-27 means moving the decimal point 27 places to the left, or a decimal point followed by 26 zeros and then the number 2.

A way of writing a number of terms of an integer power of 10 multiplied by a number greater than or equal to 1 and less than 10.

A number of the form x10, where is any integer and is between 1 and 10. Scientific notation is useful to express values that are either very large or very small.

A way of writing large numbers as powers of ten. 560000 = 5.6 x 10^5

a number expressed in the form x10 where 1£ 10 and is an integer. For example, 342.15 can be written in scientific notation as 3.4215 x 102.

A short-hand way of representing very large or very small numbers. A number expressed in scientific notation is expressed as a decimal number between 1 and 10 multiplied by a power of 10. For example, the number 4350 in scientific notation is written 4.53 x 103.

A means of compactly representing very large or very small numbers as the product of a decimal value (between 1 and 10) and a power of 10. For example, there are 86,400 seconds in a day; in scientific notation, that value would be written 8.64 × 10. A much larger example is Avogadro's number (from chemistry), which is approximately 6.02 × 10 23 . On the other end of the scale, the mass of an electron is roughly 9.11 × 10 -31 kilograms.

a shorthand method of writing very large or very small numbers using exponents in which a number is expressed as the product of a power of 10 and a number that is greater than or equal to one (1) andless than 10 (e.g., 7.59 x 105 = 759,000). It is based on the idea that it is easier to read exponents than it is to count zeros. If a number is already a power of 10, it is simply written 1027 instead of 1 x 1027.

A way to write a number as a product of a power of 10 and a number greater than or equal to 1 and less than 10

A number with the decimal point after the first nonzero digit multiplied by 10 to the appropriate power.

A method for describing very large and very small numbers through the use of powers of ten, which requires that the multiplier be a number between 1 and 10.

exponential notation. A system for reporting very small or very large numbers by writing the number as a decimal number between 1 and 10, multiplied by a power of 10. For example, 602000000000000000000000 is written in scientific notation as 6.02 x 1023. 0.000323 is written in scientific notation as 3.23 x 10-4.

uses exponents and power of 10 to represent numbers. Standard notation represents numbers used in ways you see and use everyday.

Scientific notation is a mathematical format used to write very large and very small numbers; this system avoids using a lot of zeros. In scientific notation, there is a base number (a number between 1 and 10) multiplied by a power of ten. For example, the number 250 written in scientific notation is 2.5 x 10. For another example, the number 0.000052 written in scientific notation is 5.2 x 10.

A number between 1 and 10 and multiplied by a power of 10, used for writing very large or very small numbers; for example, 2.5 × 104.

The system used when talking about very small or very large quantities. In scientific notation there is always a base unit, for example metre, Hertz, gram. Instead of using lots of zeros, scientific notation uses prefixes to indicate multiples of ten. Below is a chart of these prefixes, what they mean, and what they might measure: 10 9 giga - the number of Hertz at which satellites transmit signals 10 6 mega - the distance around the Earth 10 3 kilo - a person's weight 10 -2 centi - the width of a computer monitor 10 -3 milli - the head of a pin 10 -6 micro - -the width of human tissue 10 -9 nano - the wavelength of visible light 10 -12 pico - the width of a virus

A widely used floating-point system in which numbers are expressed as products consisting of a number between 1 and 10 multiplied by an appropriate power of 10, e.g., 562 = 5.62 x 102. (W)

if a number is written as the product of a number , where 1 10, and an integer power of 10: x 10r .

A shorthand way of writing very large or very small numbers. A number expressed in scientific notation is expressed as a decimal number between 1 and 10 multiplied by a power of 10 (e.g., 7000 = 7 x 10 or 0.0000019 = 1.9 x 10 ).

A method of representing a number as a decimal number between 1 and 10 multiplied by a power of 10, (e.g., 1.0492 x 10 to the 4 for 10,492).

Numbers entered as a number from one to ten multiplied by a power of ten. Example: 8765 = 8.765 × 10.

A form of writing a number as the product of a power of 10 and a decimal number greater than or equal to 1 and less than 10. Examples: 2,400,000 = 2.4 *106, 240.2 = 2.402 102, 0.0024 = 2.4 x10â€“3 )

Scientific notation is a notation for writing numbers that is often used by scientists and mathematicians to make it easier to write large and small numbers. A number that is written in scientific notation has several properties that make it very useful to scientists.
