In mathematics education, a number sentence is an equation or inequality expressed using numbers and mathematical symbols. The term is used in primary level mathematics teaching in the US, [ 1 ] Canada, UK, [ 2 ] Australia, New Zealand [ 3 ] and South Africa.
In mathematics, a function is a rule for taking an input (in the simplest case, a number or set of numbers) [5] and providing an output (which may also be a number). [5] A symbol that stands for an arbitrary input is called an independent variable, while a symbol that stands for an arbitrary output is called a dependent variable. [6]
[23] Analytic geometry allows the study of curves unrelated to circles and lines. Such curves can be defined as the graph of functions, the study of which led to differential geometry. They can also be defined as implicit equations, often polynomial equations (which spawned algebraic geometry). Analytic geometry also makes it possible to ...
In 2017, the Bulgarian association held a week-long Kangaroo summer camp. [8] In Canada, math contest clubs for elementary school children teach "questions typical of the Math Kangaroo contest", starting with those with a visual component and helping to develop logic and spatial reasoning . [ 9 ]
Fermat's little theorem states that if p is prime and a is coprime to p, then a p−1 − 1 is divisible by p.For a positive integer a, if a composite integer x divides a x−1 − 1, then x is called a Fermat pseudoprime to base a.
In mathematics, a quadratic equation (from Latin quadratus 'square') is an equation that can be rearranged in standard form as [1] + + =, where the variable x represents an unknown number, and a, b, and c represent known numbers, where a ≠ 0. (If a = 0 and b ≠ 0 then the equation is linear, not quadratic.)
