  Free variables and bound variables - Wikipedia, the free encyclopedia
In the lambda calculus, x is a bound variable in the term M = λ x.
Variables bound at the top level of a program are technically free variables within the terms to which they are bound but are often treated specially because they can be compiled as fixed addresses.
Similarly, an identifier bound to a recursive function is also technically a free variable within its own body but is treated specially.

 Variable - Wikipedia, the free encyclopedia
Variables are often contrasted with constants, which are known and unchanging.
Variables are useful in mathematics and computer programming because they allow instructions to be specified in a general way.
Usually, a variable is set to reside in some scope in program code, and entrance and leave of the scope coincides with the beginning and ending of a variable life, respectively.

 Variable Annuities - Free Quotes and Information
A variable annuity is a contract between you and an insurance company, under which the insurer agrees to make periodic payments to you, beginning either immediately or at some future date.
Variable annuities are not suitable for meeting short-term goals because substantial taxes and insurance company charges may apply if you withdraw your money early.
Variable annuity contracts typically have a "free look" period of ten or more days, during which you can terminate the contract without paying any surrender charges and get back your purchase payments (which may be adjusted to reflect charges and the performance of your investment).

 Free-Weight Variable Resistance
Although free weights are generally considered superior to weight machines when training for explosive strength, researchers and practitioners have for some time recognized an inherent problem when using traditional standard free-weight exercises like the parallel squat and bench press.
For the purposes of this article, we will define variable resistance as resistance that changes by increasing throughout all or part of the lifting phase of an exercise and free-weight variable resistance as the two methods in combination, i.e.
Finally, specific training outcomes can be varied by manipulating the amount of weight on the barbell and the amount of extra resistance that is applied, as well as when in the range of motion it is applied.

 Rules of Quantification
Notice that the free variable (or the constant) in the conclusion may appear at more places than the original bound variable appeared in the premise; but the free variable must appear at least in all the places where the original bound variable did.
In addition, you have a further choice: you may selectively generalize over some occurrences of the chosen free variable or constant, leaving other occurrences as they were before.
Your choice of letter for the substitution must allow these conditions to be satisfied: the newly bound variable must occur in the conclusion everywhere the original free variable occurred in the premise; and the newly bound variable must occur in the conclusion only where the original free variable occurred in the premise.

The insurance company guarantees payment of a minimum amount plus an additional sum according to the performance of a separate account, which is usually invested in equities, stocks, bonds, money market funds or other relatively high-yielding securities.
Unlike whole life insurance, variable life insurance allows you to manage your own investment portfolio, which is why it tends to be the most expensive type of cash value insurance.
One important thing that people must realize, since you are in completely control of your portfolio, if you are not that knowledgeable in the investing area, please consult with an advisor before you make any bad decisions.
