Question

расскажи по какому правилу работает вычислительная машина если она вычисляет значение числового выражения +(13-5) после того.как в нее поступает число.Поработай за эту машину и запиши какое число будет на выходе если на вход подать число 2.7.10

Answer 1

1. 2+(13-5)=10
2.7+(13-5)=15
3.10+(13-5)=18
Вот и всё)

#### How a Computer Calculates Numeric Expressions Computers follow a set of rules and principles to calculate numeric expressions. The process involves several steps, including parsing the expression, evaluating it, and producing a result. Let's break down the process step by step: 1. **Parsing the Expression**: When a computer receives a numeric expression, it first needs to parse it to understand its structure. This involves breaking down the expression into individual components, such as numbers, operators, and parentheses. In the given example, the expression is `(13-5)`. 2. **Evaluating the Expression**: Once the expression is parsed, the computer evaluates it by following the order of operations. The order of operations, also known as the precedence of operators, determines the sequence in which different operations are performed. The common order of operations is as follows: - Parentheses: Operations inside parentheses are evaluated first. - Exponents: Exponentiation operations are performed next. - Multiplication and Division: Multiplication and division operations are evaluated from left to right. - Addition and Subtraction: Addition and subtraction operations are evaluated from left to right. In the given expression `(13-5)`, the subtraction operation is performed first, resulting in the value `8`. 3. **Outputting the Result**: After evaluating the expression, the computer outputs the final result. In this case, the result of `(13-5)` is `8`. #### Calculation with Input Number Now, let's work through an example where the input number is `2.7.10`. 1. **Parsing the Expression**: The computer will parse the expression `2.7.10` and identify it as a single number. 2. **Evaluating the Expression**: Since there are no operations or parentheses in the expression, there is nothing to evaluate. The number `2.7.10` remains unchanged. 3. **Outputting the Result**: The computer will output the number `2.7.10` as the final result. Therefore, if the input number is `2.7.10`, the output of the calculation will also be `2.7.10`. Please note that the given input number `2.7.10` seems unusual and may not conform to standard numeric formats. If you have any additional information or clarification regarding the input, please let me know, and I'll be happy to assist you further.
