# BASIC ALGEBRA GLOSSARY

Mr. X is glad to provide video presentations of hundreds of basic algebra glossary terms. The basic algebra glossary is part of a complete math glossary available free of charge on the website. All basic algebra glossary terms are provided free of charge to all users.
Title Description
Half-Life When some entity experiences exponential decay (reduction or diminution) the times it takes to lose half of its size (or strength) is its Half-Life.
Height Altitude.
How tall something is, measured in some perpendicular fashion to the "bottom" is its height.
Hexahedron A six-faced polyhedron is termed a Hexahedron.
High Quartile The 75th percentile.
Also upper quartile.

Horizontal Horizontal comes from orientation like the horizon; parallel to the "flat" surface of the earth; perpendicular to vertical.
Hypotenuse The longest side of a right triangle is the Hypotenuse; it is always opposite the 90-degree angle (or right vertex).
Hypothesis In a biconditional statement the hypothesis is followed by a conclusion.
In the scientific method, the hypothesis is the conjecture to be proved or disproved.
