Natural number : A natural number is any of the numbers 1,2,3,...
Select all natural numbers.
Area : The amount of unit squares that is needed to cover a 2-dimensional shape.
Base : When using the height of a triangle or parallelogram (for example in an area calculation), base refers to the side of the triangle or parallelogram that the height starts out at. In a logarithm $\log_{b}x$ or power $b^x$ base refers to the number $b.$
Centimeter : A centimeter ($cm$) is $\frac{1}{100}$ of a meter.
Half : A Half is the number equal to $\frac{1}{2}=0.5.$
Height : In a triangle a height (or altitude) is the shortest line segment that connects a side to its opposing corner. A height of a triangle is perpendicular to the side is started at. The three heights of a triangle intersect in a point, the so called orthocenter of the triangle. In a parallelogram the height is the shortest distance between two opposing sides. In a pyramid the height is the shortest distance between the base area and the corner of the pyramid that is not part of the base area. In a prism the height is the shortest distance between the two base faces.
Product : A product is the result of a multiplication.
Square centimeter : Square centimeter or $cm^2$ is a unit of measurement for measuring area. 1 square centimeter is the area of a square with side length 1 $cm,$ so 10,000 $cm^2$ are one $m^2.$
Triangle : A triangle is a polygon with three corners and three sides. You can calculate the area of a triangle by multiplying half the length of the base by the height on that base. The sum of the interior angles in a triangle is always $180^{\circ}.$
What is the area in square cm of a triangle with a base of 2 cm and a height of 1?
Denominator : The denominator of a fraction $\frac{a}{b}$ is the number $b$ below the fraction bar.
Division : Division is the mathematical operation that divides objects equally into groups. More generally $x\div y$ is defined as the number that if multiplied by $y$ equals $x.$
Fraction : A fraction is a number that can be written as $\frac{a}{b}$ with an integer $a$ and a natural numbers $b.$ A fraction $\frac{a}{b}$ is the result of the division $a\div b.$ Examples of fractions are $\frac{1}{2}, -\frac{2}{3}$ and $\frac{3}{2}.$
Multiplication : Multiplication is the mathematical operation that is a shorthand for adding the same amount several times. For example $3\cdot 4=4+4+4=12.$
Whole number : A whole number is any of the numbers $0,1,2,\ldots.$
$\frac{4}{4}\div 10=\frac{4}{?}$
