# Rewrite an expression as a sum

Site Navigation Properties of Logarithms Logarithmic functions and exponential functions are connected to one another in that they are inverses of each other. You may recall that when two functions are inverses of each other, the x and y coordinates are swapped. A variable is a letter that represents a number. Don't let the fact that it is a letter throw you. Since it represents a number, you treat it just like you do a number when you do various mathematical operations involving variables. Evaluating an Expression You evaluate an expression by replacing the variable with the given number and performing the indicated operation. Value of an Expression When you are asked to find the value of an expression, that means you are looking for the result that you get when you evaluate the expression.

So keep in mind that vary means to change - a variable allows an expression to take on different values, depending on the situation. For example, the area of a rectangle is length times width. Well, not every rectangle is going to have the same length and width, so we can use an algebraic expression with variables to represent the area and then plug in the appropriate numbers to evaluate it.

So if we let the length be the variable l and width be w, we can use the expression lw. If a given rectangle has a length of 4 and width of 3, we would evaluate the expression by replacing l with 4 and w with 3 and multiplying to get a value of 4 times 3 or Plugging in the corresponding value for each variable and then evaluating the expression we get:Complex Materialized Views.

Rewrite capability with complex materialized views is limited to SQL text match-based rewrite (partial or full). A materialized view can be defined using arbitrarily complex SQL query expressions, but such a materialized view is treated as complex by query rewrite.

Algebra > Sequences and Series > Series and Sigma Notation. Page 1 of 6. Series and Sigma Notation. OK, so we know what a sequence is -- it's a list of numbers (or other things) that changes according to some pattern. So, what's a series?

Easy! A SERIES is the sum of a . Rewriting query expressions is a simple and yet safe and powerful technique to modify queries dynamically at runtime. Changing a LINQ expression dynamically (at runtime) depending on the user’s input is one of the problems that is often discussed in forums and blogs.
