What is the value of the expression \(2 *(3+4)\) in Python?

In Python, and in most programming languages, parentheses play a crucial role in determining the order of operations. This concept is often referred to as 'parentheses evaluation'. Whenever you see an expression with parentheses, always evaluate the inside of the parentheses first. For example, in the expression \(2 * (3 + 4)\), the part inside the parentheses is \(3 + 4\). So, you should start by evaluating \(3 + 4\) which equals 7. After doing this, you replace the parentheses part of the expression with the result, turning \(2 * (3 + 4)\) into \(2 * 7\). This method ensures that you respect the mathematical order of operations, also known as BODMAS/BIDMAS (Brackets, Orders (i.e., powers and square roots, etc.), Division and Multiplication, Addition and Subtraction).

Multiplication is one of the fundamental operations in arithmetic and is commonly found in many equations and expressions. In our given example, once we evaluated the parentheses, the expression became \(2 * 7\). When you encounter a multiplication operation in an expression, you simply multiply the numbers together. In Python, the asterisk (*) symbol is used to denote multiplication. Thus, evaluating \(2 * 7\) gives us 14. Remember, multiplication is performed after any operations inside parentheses but before addition or subtraction, according to the order of operations.

Basic arithmetic includes the operations of addition, subtraction, multiplication, and division. These operations are essential building blocks for more complex mathematical concepts. In Python, like many programming languages, there are specific symbols associated with each of these operations:

• Addition is denoted by the plus (+) symbol.
• Subtraction is denoted by the minus (-) symbol.
• Multiplication is denoted by the asterisk (*) symbol.
• Division is denoted by the forward slash (/) symbol.

In the expression \(2 * (3 + 4)\), we used both addition and multiplication. Firstly, we performed the addition inside the parentheses: \(3 + 4 = 7\). Then we performed the multiplication with the result of the addition: \(2 * 7 = 14\). Understanding these basic operations and the correct order in which they should be performed is essential when solving mathematical problems in Python or any other programming environment.
