Math History

The abacus is the original mechanical counting device. It was likely first used over five thousand years ago, and used beads to keep track of numbers.

History has it that Fibonacci was a great mathematician who, in the thirteenth century, was involved in a mathematical competitions. In one of these competitions he was given the problem of how fast rabbits would breed under ideal circumstances. The problem set the limit of each pair giving birth to just two offspring, and none of the rabbits die.

In the process of solving the problem, the sequence of numbers now called the Fibonacci Sequence was proposed.

The sequence begins with 0, 1 and the sequence of new numbers is the sum of the previous two numbers. Thus we have the sequence:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 etc.

This sequence has also been determined to approximately represent many facets of nature, for example the manner in which a trees branches form, the formation of a delta at a rivers end, efc.

the fastest receiver in the nfl combine 2010 is Jacoby Ford at 4.28s

i believe that's the fastest for a receiver because the fastest 40yd dash time was set by Chris Johnson in the '08 combine at 4.24s

The use of "other" in the question implies that you are already aware of some contribution(s). However, you have not shared that information. Unfortunately we, at Answers.com, have not yet mastered the art of reading minds over the internet and so we do not know which contributions you are already aware of. We cannot, therefore, determine whether the contributions we know of are already in known to you or are "other".

There can be no person who is singlehandedly responsible for the founding of alerbra. This is because algebra is a classification of a certain type of math. Therefor there is a vast amount of people who contributed to the upbringing of algebra.

I don't believe anyone suggested it, certainly no-one that could be named at least. Long before we had digital computers we had machines that were fully capable of processing binary information. The Jacquard loom is a prime example which pre-dates Charles Babbage's early computer designs. Although Babbage dabbled with decimal machines, even he saw the benefits of using binary; by far the simplest method of implementing a numeric system at the machine level.

I believe the Aztecs mathematicians were first to have a concept of zero and negative numbers.

Math is used extensively in photography to determine various aspects related to the image and its quality. Here are some of the ways math is used in photography:

Exposure: The process of capturing an image involves exposing the camera sensor or film to light. The three elements that control the amount of light entering the camera are aperture, shutter speed, and ISO. These elements are all measured in mathematical values, and a basic understanding of math is needed to determine the correct exposure settings for a particular scene.

Focal Length: The distance between the lens and the camera sensor or film is called the focal length. A longer focal length results in a narrower field of view and a closer image. Calculating the focal length is based on mathematical formulas.

Depth of Field: Depth of field is the area in focus in the image. It is determined by the aperture, focal length, and distance from the focal point. Understanding the math behind depth of field can help photographers achieve the desired effect of having a sharp or blurred background.

Composition: Composition in photography refers to the arrangement of elements in the image. The rule of thirds is a compositional guideline that suggests dividing the image into thirds both horizontally and vertically, and placing important elements along these lines or their intersections. This guideline is based on mathematical principles and is believed to create a more balanced and visually pleasing composition.

In summary, math plays a crucial role in many aspects of photography, including exposure, focal length, depth of field, and composition. Try this recommendation from an expert in photography: ₕₜₜₚₛ://www.dᵢgᵢₛₜₒᵣₑ₂₄.cₒₘ/ᵣₑdᵢᵣ/₄₆₅₇₄₆/ₛₑₜᵢ₀₄/

3n(n+1] + 5 is the nth term

'4'

Remember the 4 times multiplication table.

1 x 4 = 4

2 x 4 = 8

3 x 4 = 12 (This is the answer)

4 x 4 = 16

5 x 4 = 20

6 x 4 = 24

7 x 4 = 28

8 x 4 = 32

9 x 4 = 36

10 x 4 = 40

11 x 4 = 44

12 x 4 = 48

Greece is relatively poor in natural resources. Bauxite, from which aluminum is produced, is the most significant mineral resource, and there are also deposits of asbestos, nickel, magnesite, and marble. The country has little black coal, and its lignite (brown coal) is of poor quality. The reserves of other commercially important minerals, such as chromium, copper, uranium, and magnesium, are relatively small. Greece's small petroleum deposits, located under the Aegean Sea near the island of Thasos, are rapidly being depleted. There are no significant reserves of natural gas.

Greece's forests, probably abundant in ancient times, have been significantly depleted. Subsequent soil erosion has made reforestation efforts difficult. Although much of Greece's soil is rocky and dry, the country's mountains are interspersed with small valleys where the soils are of the rich Mediterranean terra rosa (red earth) variety. Cultivated fields and orchards cover 30 percent of the country. The fertile plains of Thessaly, Macedonia, and western Thrace are prime agricultural areas.

The main reason we employ Hindu-Arabic numbers so widely is that it is much easier to do arithmetic with them than it is with Roman numerals. Roman numerals are fine if you just want to represent one number, but if you want to add CMLVII to MCXXXIV then basically you have to do it in your head, because there is no column- for -place system as we use today. Adding 957 to 1134 is much easier if you arrange them under each other, lining up the units, tens, hundreds etc.

The Pythagorean Theorem says that in a right triangle, the sum of the squares of the two right angle sides will always be the same as the square of the hypotenuse if your not sure I'm probably wrong.kjyukkuyyku

^^ yeah that's right. the formula is A squared + B squared = C squared
