Equation, in mathematics, a statement, usually written in symbols, that states the equality of two quantities or algebraic expressions, eg, x+3=5 the quantity x+3, to the left. E = mc 2, equation in german-born physicist albert einstein’s theory of special relativity that expresses the fact that mass and energy are the same physical entity and can be changed into each other in the equation, the increased relativistic mass (m) of a body times the speed of light squared (c 2) is equal to the kinetic energy (e) of that body. Linear equations like y = 2x + 7 are called linear because they make a straight line when we graph them these tutorials introduce you to linear relationships, their graphs, and functions. An equation is a mathematical statement that two things are equal it consists of two expressions, one on each side of an 'equals' sign for example: this equation states that 12 is equal to the sum of 7 and 5, which is obviously true in an equation, the left side is always equal to the right side.

Basics of algebra algebra is a division of mathematics designed to help solve certain types of problems quicker and easier algebra is based on the concept of unknown values called variables, unlike arithmetic which is based entirely on known number values. An equation is a mathematical expression stating that two or more quantities are the same as one another, also called an equality, formula, or identity.
Equation is an independent women's fashion boutique located in edina minnesota shop the latest contemporary designer brands at equationmncom. A mathematical statement used to evaluate a valuean equation can use any combination of mathematical operations, including addition, subtraction, division, or multiplicationan equation can be already established due to the properties of numbers (2 + 2 = 4), or can be filled solely with variables which can be replaced with numerical values to get a resulting value. Henderson-hasselbalch equation a formula for calculating the ph of a buffer solution such as blood plasma, ph = pk a + log [ba/ha] [ha] is the concentration of a free weak acid [ba] the concentration of the ionized form of this acid pk a the acid dissociation constant, a measure of the ionization equilibrium of the acid. Equation: equation, statement of equality between two expressions consisting of variables and/or numbers in essence, equations are questions, and the development of mathematics has been driven by attempts to find answers to those questions in a systematic way equations vary in complexity from simple.
Easily create mathematical equations, formulas and quizzes intuitively type or handwrite, with no tricky math code to learn. An equation says that two things are equal it will have an equals sign = like this: 7 + 2 = 10 − 1 that equation says: what is on the left (7 + 2) is equal to what is on the right (10 − 1.
