123e2

123e2 is a notation representing a number in scientific notation. The "123" represents the significand, and "e2" indicates that the significand should be multiplied by 10 raised to the power of 2. Therefore, 123e2 is equivalent to 123 multiplied by 100.

To calculate the value of 123e2, we perform the multiplication: 123 * 100 = 12300. This means that 123e2 represents the integer 12,300. Scientific notation is often used to express very large or very small numbers in a more compact and manageable form. In this case, 123e2 is a concise way to write 12,300.

The "e" notation, also known as E notation or exponent notation, is common in calculators, computer programming languages, and scientific contexts. It serves as a shorthand for expressing powers of ten. For example, a number like 6.022e23 represents 6.022 followed by 23 zeros. Similarly, a number like 1.5e-9 represents 1.5 multiplied by 10 to the power of -9, which is 0.0000000015. Thus, 123e2 fits within this established system of numerical representation.
