  base (mathematics) - Hutchinson encyclopedia article about base (mathematics)
For example, the logarithm of 100 to the base ten is 2.
For bases beyond 10, the denary numbers 10, 11, 12, and so on must be replaced by a single digit.
Thus in base 16, all numbers up to 15 must be represented by single-digit ‘numbers’, since 10 in hexadecimal would mean 16 in decimal.

 Base (mathematics) - Wikipedia, the free encyclopedia
In mathematics, the base or radix is the number of various unique symbols (digits), including zero, that a positional numeral system uses to represent numbers in a given counting system.
For example, the decimal system, the most common system in use today, uses base ten, hence the maximum number a single digit will ever reach is 9, after this it is necessary to add another digit to achieve a higher number.
When describing radix in mathematical notation, the letter b is generally used as a symbol for this concept, so, for a binary system, b equals 2.

 AllRefer.com - numeration (Mathematics) - Encyclopedia
In any place value system of numeration, a base number must be specified, and groupings are then made by powers of the base number.
The position of a numeral in a grouping indicates which power of the base it is to be multiplied by.
The binary system uses base 2 and is important because of its application to modern computers.

Mathematics and Science science reform efforts, and the higher academic standards included in those efforts, require far-reaching and difficult changes in the practice of teaching mathematics and science.
Despite increasing enrollment in higher level mathematics and science courses, the Miami-Dade student population as a whole is performing below the state average on the FCAT and below the national median in mathematics and science as measured by the Stanford-8, except in elementary mathematics.
Student performance in mathematics, as measured through the FCAT grade 10, in 1999, showed that 38% of the student standard curriculum population of Miami-Dade County Public Schools scored at the lowest level, level I. This level indicates little success with the challenging content of the Sunshine State Standards.

 Maya mathematics
(Base 20 is vigesimal.) They also used a system of bar and dot as "shorthand" for counting.
Because the base of the number system was 20, larger numbers were written down in powers of 20.
Base twenty was also used in their calendar, which is a major portion of these pages because calendars are developed by astronomers for keeping track of time.

We do not know the date of these mathematical achievements but it seems certain that when the system was devised it contained features which were more advanced than any other in the world at the time.
In fact it is worth noting that although the system is base 20 it only has three number symbols (perhaps the unit symbol arising from a pebble and the line symbol from a stick used in counting).
The Long Count is based on a year of 360 days, or perhaps it is more accurate to say that it is just a count of days with then numbers represented in the Mayan number system.

 Early Childhood Mathematics
In mathematics as in literacy, children who live in poverty and who are members of linguistic and ethnic minority groups demonstrate significantly lower levels of achievement [14-17].
In the key areas of mathematics, researchers have at least begun to map out trajectories or paths of learning--that is, the sequence in which young children develop mathematical understanding and skills [21, 58, 59].
For example, there are books with mathematical concepts in the reading corner, and clipboards and wall charts are placed where children are engaged in science observation and recording (e.g., measuring and charting the weekly growth of plants) [65, 66, 68-71].

 A BASE Mathematics Project
Participants of the January Seminar (encompassing representative mathematics faculty from the junior high through college/university levels, articulation officers, and administrators) were divided into groups based on county affiliation.
A major outcome of the September Workshop series, participating mathematics faculty developed an agreed-upon common set of concepts that students have the most difficulty learning and a set of concepts which students should know prior to entering each of the targeted algebra courses.
Algebra instructors who attended the workshop identified mathematical concepts that students should have learned prior to entering their respective level of algebra as well as those algebraic concepts that students in their respective level had the most difficulty in learning.

However the Babylonian civilisation, whose mathematics is the subject of this article, replaced that of the Sumerians from around 2000 BC The Babylonians were a Semitic people who invaded Mesopotamia defeating the Sumerians and by about 1900 BC establishing their capital at Babylon.
It was a positional system with a base of 60 rather than the system with base 10 in widespread use today.
In our article on Pythagoras's theorem in Babylonian mathematics we examine some of their geometrical ideas and also some basic ideas in number theory.

Mathematics is not a mere collections of facts or coincidences [2] nor a set of abstract formulas invented for the sole pleasure of the intellect.
Mathematics is a unique discipline which implicitly comprises its own logic and which carries with it a certainty of substance absent in other areas of study.
It is the classification instrument par excellence also with respect to encyclopaedic works such as the Encyclopaedia of Mathematics [3], seminal work born on the shores of the Moscova and now developed on ancient ferries under the guidance of M. Hazewinkel [4].

 Chemistry: Acids and Bases
This is because the conjugate base of a strong acid is very weak and cannot undergo hydrolysis.
An acid-base titration is when you add a base to an acid until the equivalence point is reached which is where the moles of acid equals the moles of base.
For the titration of a strong base with a weak acid, the equivalence point is reached when the pH is greater than seven (7).

 Binary, Octal, Hexadecimal Systems, Base Convertion
It was easier and more natural to write a generic base converter than doing anything special for the binary system.
Please note that the number of digits in any base (radix) N is exactly the same number N. For example, in the binary (N = 2) system there are two digits: 0 and 1; in the decimal (N = 10) there are ten of them: 0,1,2,3,4,5,6,7,8,9.
Representation of a number in a system with base (radix) N may only consist of digits that are less than N. (The converter works this way: first type a number in the base you wish to convert from.
