binomial (2): In algebra, an expression consisting of the sum or difference of two monomials (see the definition of monomial ), such as 4 a - 8b.
decimal fraction (5): A decimal fraction is a fraction where the denominator is a power of ten. Decimal fractions are commonly expressed without a denominator, the decimal separator (comma) being inserted into the numerator at the appropriate position. For example: 5.25 is a decimal fraction or a decimal.
expanded form (1): The expanded form of an algebraic expression is the equivalent expression without parentheses. For example, the expanded form of (a + b)2 is a 2 + 2 ab + b2.
fraction (4): Any number that does not represent a whole is called a "fraction". A fraction can be represented as one number divided by another non-zero number.
inequality (7): A relationship between two quantities indicating that one is strictly less than or less than or equal to the other.
irrational number (2): A number that cannot be represented as an exact ratio of two integers. For example, the square root of 2 or π.
power (3): An exponent of a number, such as in Xn.
quadratic function (1): A function given by a polynomial of degree 2.
