Addition : Addition is the mathematical operation that describes increasing a number by an amount equal to a second number. The mathematical symbol for addition is the plus sign $+.$ The term addition is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.
Decimal point : The point in a decimal separating the digits representing multiples of wholes from the digits representing fractions of wholes.
Digit : A digit is a symbol used in the representation of a number.
Number : A number $x$ is a mathematical symbol representing a quantity.
Subtraction : Subtraction is the mathematical operation that describes decreasing a number by an amount equal to a second number. The mathematical symbol for subtraction is the minus sign $-.$ The term subtraction is also used for a generalization of this basic operation on numbers to functions, vectors and matrices.
Zero : The number 0.
What is 0.9-0.04?
Cube : A cube is a three-dimensional shape with 6 faces that are all squares. A cube has 8 corners and 12 edges.
Cubic meter : A cubic meter or $m^3$ is a unit to measure volume. A cubic meter is the volume of a cube with edge length 1 meter.
Edge : An edge of a shape is a line segment between two corners of that shape.
Length : Length is the attribute of a one-dimensional shape that can be measured with a measuring tape.
Volume : Volume refers to the size of a three-dimensional objects measured by how many unit cubes it would take to fill the shape.
What is the volume in cubic m of a cube with edge length 5 m?
Denominator : The denominator of a fraction $\frac{a}{b}$ is the number $b$ below the fraction bar.
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 $\frac{3}{2}.$
Numerator : The numerator of a fraction $\frac{a}{b}$ is the number $a$ above the fraction bar.
Product : A product is the result of a multiplication.
Reduced fraction : A reduced fraction (or simplified fraction or fraction in simplified form or fraction in simplest form) is a fraction $\frac{a}{b}$ such that $a$ and $b$ do not have any common factors bigger than 1. For example the reduced fraction of the fraction $\frac{4}{6}$ is $\frac{2}{3}.$
What is $\frac{5}{10}\cdot\frac{3}{5}$ as a reduced fraction a/b?
