HegartyMaths was created by co-founders and teachers Colin Hegarty and Brian Arnold. In 2011 they started to make maths videos on YouTube to support their own classes with maths homework and revision. Since the videos were freely available on YouTube, students from all over the country and the world started using the videos too.
Compu-Math: Fractions was the first program created in the Compu-Math series, being introduced in Edu-Ware's March 1, 1980 catalog.Fractions six learning modules include tutorials on definitions, common and lowest denominators, fraction addition, fraction subtraction, fraction multiplication, and fraction division.
Since Lady Gaga's "Bad Romance" in 2009, every video that has reached the top of the "most-viewed YouTube videos" list has been a music video. In November 2005, a Nike advertisement featuring Brazilian football player Ronaldinho became the first video to reach 1,000,000 views.

Holt began moving from steam to gasoline-powered designs, and in 1908 brought out the 40 ...
A sequence is a function on the natural numbers, so every sequence ,, … in a topological space can be considered a net in defined on . Conversely, any net whose domain is the natural numbers is a sequence because by definition, a sequence in X {\displaystyle X} is just a function from N = { 1 , 2 , … } {\displaystyle \mathbb {N} =\{1,2 ...
The ordinary generating function of a sequence can be expressed as a rational function (the ratio of two finite-degree polynomials) if and only if the sequence is a linear recursive sequence with constant coefficients; this generalizes the examples above. Conversely, every sequence generated by a fraction of polynomials satisfies a linear ...
Achaea janata, the castor semi-looper or croton caterpillar, is an erebid moth, the caterpillars of which are termed 'semi-loopers' due to their mode of locomotion. It is found from the Indo-Australian tropics and subtropics, extending south to New Zealand and east through the Pacific archipelagoes to Easter Island . [ 2 ]
