Exponents are a way to express repeated multiplication of the same number. When you see a number like \(7^2\), the 2 is the exponent, and it tells you to multiply the base, which is 7, by itself. In our example, we have \(7^2\), meaning you multiply 7 by itself: \(7 \times 7\). This equals 49. Exponents simplify expressions and clearly convey the instruction "multiply this number by itself" a certain number of times.
Understanding exponents is essential, as they are used frequently in mathematics to express large numbers in a concise form. When tackling exponents in an expression, compute them before doing any addition, subtraction, multiplication, or division, unless specifically directed otherwise by parentheses.

The order of operations is a set of rules to follow when solving mathematical expressions. It ensures consistency and accuracy in solving math problems. The common acronym used is PEMDAS:

• Parentheses
• Exponents
• Multiplication and Division (from left to right)
• Addition and Subtraction (from left to right)

In our task, after calculating the exponent \(7^2 = 49\), the next step according to PEMDAS is multiplication. So, we proceed with multiplying 2 by 49. Following these rules helps you systematically break down and correctly simplify expressions.
Always start with operations in parentheses, then move to exponents, and so on, ensuring each step aligns with the correct sequence.

Basic arithmetic deals with addition, subtraction, multiplication, and division—the building blocks of more advanced math. It's crucial to grasp how these operations work together.
Our specific problem involved the operation of multiplication, which is one of the most straightforward arithmetic skills. After calculating \(7^2\) as 49, we multiply: \(2 \times 49 = 98\). This result unfolds from following the proper sequences of calculations, as defined by the order of operations.
Practicing basic arithmetic ensures a solid foundation, making it easier to handle more complex mathematical problems. Try to get comfortable with these operations separately and in combination, as they're fundamental to every mathematical topic you'll encounter.
