Final answer:
TI calculators come with a set of pre-installed applications that provide additional functionality.
Step-by-step explanation:
The number of built-in applications in a TI calculator depends on the specific model. However, most TI calculators come with a set of pre-installed applications that provide additional functionality to the calculator.
For example, the TI-84 Plus, one popular model, comes with several built-in applications such as the Finance application, which allows you to perform financial calculations, and the Probability Simulation application, which helps with probability and statistics calculations.
To determine the number of built-in applications on a specific TI calculator, you can refer to the calculator instructions available on the TI website or in the appendix of the calculator manual.
