Base 3 math, called ternary, uses three digits: 0, 1, and 2. Each position represents a power of 3, so the places grow as 1, 3, 9, 27, 81, and so on. Ternary packs more informat...

A perfect square root of a number is an integer that, when multiplied by itself, yields that number. For example, the square root of 16 is 4 because 4 times 4 equals 16. Perfect...

The commutative property states that the order of numbers in an operation does not change the result. For addition, a + b = b + a; for multiplication, a × b = b × a. This prop...

A parabola is the set of all points in a plane that are equidistant from a fixed point called the focus and a fixed line called the directrix. In practical terms, parabolas desc...

The commutative property states that changing the order of two operands does not change the result for a given operation. In elementary math, addition and multiplication of real...

Half is the result of dividing one whole into two equal parts. In fraction form, it is written as 1/2, where 1 is the numerator (the part being considered) and 2 is the denomina...

A complex conjugate refers to a pair of complex numbers with identical real parts and opposite imaginary parts. If z = a + bi, its conjugate is denoted as z̄ or z*, where z̄ =...

Names for addition refer to the words and phrases used to describe the operation of combining quantities, and they vary by context, grade level, and regional conventions. This g...

A formal proof in geometry is a finite, linear sequence of statements, each of which is either an assumption, an axiom, a previously proved theorem, or follows by a specified ru...

A quadratic term is the part of an expression that contains a variable raised to the power of two, written as ax², where a is a nonzero constant and x is the variable. It defin...
