Question

A program checks to see if the input is valid using

numbers
operators
logic
output​

Answer 1

The question pertains to input validation in programming within Computers and Technology, focusing on the correct handling of numbers and logical operations to ensure the accuracy of a program's "output".

Step-by-step explanation:

The subject of the question involves a program that checks for valid input using numbers, operators, and logic to produce an output. In the field of Computers and Technology, especially when dealing with programming, it is critical to ensure that the input is valid to avoid errors and ensure the program runs as expected. Valid input usually means that the data entered corresponds to what the program expects, whether it be in the form of numbers, text, or other data types.

Numbers are fundamental in programming and are composed of digits (0-9). They can be represented in various forms including whole numbers, decimals, and even in scientific notation. Understanding how to handle numbers and their corresponding operators is essential in ensuring that the mathematical model of the program is constructed appropriately. For example, when numbers are added in a program, whether you add 2 + 3 or 3 + 2, the result should be the same, demonstrating the commutative property of addition.

Answer 2

The question relates to a program's input validation process involving numbers, operators, and logic, reflecting principles of both math and computer programming. It highlights the importance of accurately constructed mathematical models and the reliability of computational outcomes dependent on correct inputs.

Step-by-step explanation:

The question pertains to a program's capability to check whether an input is valid, which involves using numbers, operators, logic, and output. These concepts are critical in both math connections and computational logic within computer programming. For example, when constructing a mathematical model within a program, it is essential to ensure that the chosen science and mathematics principles have been properly applied. In computational terms, numbers are composed of digits (0-9) and can include a decimal point for more precise values.

The rules for the sign in a calculated answer dictate how operators apply to these numbers. For instance, just as in mathematics where 2 + 3 yields the same result as 3 + 2, computational logic must also adhere to these mathematical rules. Additionally, checking results, such as verifying that I₁ = 12 + 13 holds true in a program, is a part of validating the logic used in the model.

Tools like calculators, especially models like the TI-83 or TI-84 series, are recommended to students for computation and model validation. However, the accuracy of the calculations also depends on the correct entry of numbers into these calculators or any program designed for computation. It underlines the fact that the reliability of an answer from a calculator or a computer program is only as good as the input provided.
