The study was conducted at two different primary schools, at the first school a fourth grade class was selected to use FASTT Math while the fifth and sixth grade classes stood as control groups, while the second school its fourth grade class was selected to be the control group while the fifth and sixth grade classes were selected to use FASTT ...
At the Russian School of Mathematics, students begin multi-step problems as early as the first grade, learning to build on previous results to progress towards the solution. In the 1960s, collections of mathematical exercises were translated from Russian and published by W. H. Freeman and Company : The USSR Olympiad Problem Book (1962), [ 8 ...
Number theory is a branch of pure mathematics devoted primarily to the study of the integers and arithmetic functions.German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."
Although mathematics is extensively used for modeling phenomena, the fundamental truths of mathematics are independent of any scientific experimentation. Some areas of mathematics, such as statistics and game theory, are developed in close correlation with their applications and are often grouped under applied mathematics.

A visualization of the surreal number tree. In mathematics, the surreal number system is a totally ordered proper class containing not only the real numbers but also infinite and infinitesimal numbers, respectively larger or smaller in absolute value than any positive real number.
Similarly, the formal power series ring R[{[t]}] is the completion of R[t] at (t) (see also Hensel's lemma) A complete ring has much simpler structure than a commutative ring. This owns to the Cohen structure theorem, which says, roughly, that a complete local ring tends to look like a formal power series ring or a quotient of it.
Say N t denotes, at generation t, the number of individuals of the population that will reproduce, i.e. the population size at generation t. The population at the next generation, which is the population at time t+1 is: [20] + = + + where B t is the number of births in the population between generations t and t + 1, D t is the number of deaths ...
