Approximate the number using a calculator.

(Round to three decimal places.)

The value of can be approximated using a calculator and is approximately when rounded to three decimal places. This fascinating number is derived from Euler’s number, which is the base of the natural logarithm and is approximately equal to 2.71828.

Euler’s number gives us a glimpse into the world of exponential growth and decay, appearing in various fields such as finance, biology, and physics. For instance, in populations that grow continuously, our friend helps model how quickly a population can expand or contract. It’s a key player in phenomena ranging from compound interest formulas to the spread of diseases!
