In the video below we show more examples of how to substitute a value for variable in an expression, then evaluate the expression.Candela Citations CC licensed content, Shared previously Ex: Substitute and Evaluate Expressions x^2+3, (x+3)^2, x^2+2x+3. Authored by: James Sousa (Mathis...
Functions can also be evaluated for inputs that are variables or expressions. The process is the same, but the simplified answer will contain a variable. The following examples show how to evaluate a function for a variable input.Example Given f(x)=3x2+2x+1f(x)=3x2+2x+1, find f(b)...
Writing and Evaluating Algebraic Expressions Worksheets Resource Examples Definition: Inmathematics, there are instances that the value of a certain number may be unknown. A variable is a symbol, usually a letter, used to represent an unknown number. A variable, a number, or a number and variabl...

Evaluating equations works very much like evaluating expressions. However, equations, formulas, and functions have "equals" signs in them. So instead of simplifying a single expression to get a numerical value, we'll be simplifying part of an equation in order to find the value of whatever is...
The first expression, last expression, and stride expression are optional expressions that should evaluate to integers. For an n-dimensional slice, separate the definition of each slice with a comma. For example: (dbx) print arr(2:6) arr(2:6) = (2) 2 (3) 3 (4) 4 (5) 5 ...
