The abacus remains in common use as a scoring system in non-electronic table games. Others may use an abacus due to visual impairment that prevents the use of a calculator. [1] The abacus is still used to teach the fundamentals of mathematics to children in most countries. [citation needed]
Time value of money problems involve the net value of cash flows at different points in time. In a typical case, the variables might be: a balance (the real or nominal value of a debt or a financial asset in terms of monetary units), a periodic rate of interest, the number of periods, and a series of cash flows. (In the case of a debt, cas
It continues that "it has been the experience of all previous Olympic Games that the press of the world insist on exploiting the aspect of national rivalry by creating and publishing a wholly unofficial point score of their own devising, most often on the basis of 10, 5, 4, 3, 2, 1 points for the six places recognized on the table of honour".
Inflection points in differential geometry are the points of the curve where the curvature changes its sign. [ 2 ] [ 3 ] For example, the graph of the differentiable function has an inflection point at ( x , f ( x )) if and only if its first derivative f' has an isolated extremum at x .
A percentage point or percent point is the unit for the arithmetic difference between two percentages.For example, moving up from 40 percent to 44 percent is an increase of 4 percentage points (although it is a 10-percent increase in the quantity being measured, if the total amount remains the same).

The x-coordinates of the red circles are stationary points; the blue squares are inflection points.. In mathematics, a critical point is the argument of a function where the function derivative is zero (or undefined, as specified below).
Time zones of the world. A time zone is an area which observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
Artificial intelligence (AI), in its broadest sense, is intelligence exhibited by machines, particularly computer systems.It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals.
