... - A mathematical phrase made up of a combination of variables and/or numbers and operations. Expression with variables are also called algebraic expressions. Expressions with variables must have a number to substitute the variable and then solve. • 5n, n = 4. 5 x 4 = 20; 4x – 7; (5 x 2) – 6/3; … • E ...

Systems of Equations
... Solve the system using elimination. 5x – 2y = –15(4) Since neither variable will drop out if the equations are added together, we must multiply one or both of 3x + 8y = 37 the equations by a constant to make one of the ...

Student Handout
... In Problem 2, you explored the affect of multiplying an equation by a constant and found that (although it may change the appearance) it does not change the equality relationship that existed in the original equation. In this problem, an additional linear equation is introduced to form a system of t ...

Partial differential equation
In mathematics, a partial differential equation (PDE) is a differential equation that contains unknown multivariable functions and their partial derivatives. (A special case are ordinary differential equations (ODEs), which deal with functions of a single variable and their derivatives.) PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a relevant computer model.PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.
