The average cost of gastric sleeve surgery is between $12,500 and $24,000 with an average of $15,500. The cost of such a surgery can be varied depending on a number of factors including location of the procedure.
Simulation embodies the principle of ``learning by doing'' --- to learn about the system we must first build a model of some sort and then operate the model. The use of simulation is an activity that is as natural as a child who role plays. Children understand the world around them by simulating (with toys and figurines) most of their interactions with other people, animals and objects.
Time is continuous, as in the real world. Another example of live simulation is testing a car battery using an electrical tester. Virtual simulations typically involve humans and/or equipment in a computer-controlled setting. Time is in discrete steps, allowing users to concentrate on the important stuff, so to speak.
