## How do you do mathematical model expressions?

An expression is **a set of terms combined using the operations +, , x or. , for example 4 x u2212 3 or x 2 x y + 17 . An equation states that two expressions are equal in value, for example. 4 b u2212 2 6 . An identity is a statement that is true no matter what values are chosen, for example.**

## How do you draw an expression model?

An algebraic model **uses algebra to describe a real-world situation. We can use algebraic models to solve problems. By taking the information given in a problem, we can represent quantities using variables and then set up an equation using those variables. This equation is our algebraic model.**

## How do you solve mathematical models?

Though **equations and graphs are the most common types of mathematical models, there are other types that fall into this category. Some of these include pie charts, tables, line graphs, chemical formulas, or diagrams.**
