But where does it come from? Now suppose the bank compounds the interest every six months, but only offers half the interest rate, or 50 percent. And why is it important? But one constant that's equally important, though perhaps less well known, is Euler's constant, e. This constant shows up all the time in math and physics, but where does it come from? There are many ways of calculating the value of e, but none of them ever give a totally exact answer, because e is irrationaland its digits go on forever without repeating.
In this case, you'd end up with 2.25 times your initial investment after one year.
Gear-obsessed editors choose every product we review. Suppose you put some money in the bank, and the bank compounds that money annually at a rate of 100 percent. Now It's Scrap.
Of course, e is more than just any number. Math has many important constants, like pi and i, the imaginary number that is equal to the square root of negative one.

Suppose the bank offered 8.3 percent (1/12 of 100 percent) interest compounded every month, or 1.9 percent (1/52 of 100 percent) interest compounded every week. In calculus, which is all about finding slopes and areas, you can imagine that e is a pretty important number. We may earn commission if you buy from a link. If we make n equal to the number of times that interest is compounded, than the interest rate is the reciprocal, or 1/n. It's also an important number in physics, where it shows up in the equations for waves, such as light waves, sound waves, and quantum waves.
In that case, you'd make 2.61 and 2.69 times your investment.
The constant e was discovered in the early 18th century by mathematician Leonard Euler. But it isknown to over 1 trillion digits of accuracy!
However, this did not contain the constant itself, but simply a list of logarithms calculated from the constant.
Let's keep going. This is the question that Bernoulli was trying to answer, but it took 50 years for Euler to come along and solve it. It has several meanings in mathematics. For example, the value of (1 + 1/n)n approaches eas n gets bigger and bigger: Of course, e is more than just any number. Narwhal Changed the Navy Forever. It's one of the most useful mathematical constants.
Also called Napier's Constant or the Natural Base. Bernoulli's problem was related to compound interest. "e" also shows up in some problems of probability, some counting problems, and even the study of the distribution of prime numbers. The value of "e" is found in many mathematical formulas such as those describing a nonlinear increase or decrease such as growth or decay (including compound interest), the statistical "bell curve," the shape of a hanging cable or a standing arch. e is the only number in all of mathmatics that can be plugged into the equation y=nx for which this pattern is true. Euler was trying to solve a problem first proposed by another mathematician, Jacob Bernoulli, half a century earlier. In pure mathematics: Euler's number (e) - a constant that is highly important in higher level mathematics. E, in capitalized form, and e in lower-case, is the fifth letter of the Latin-based alphabet systems, including English. Let's write an equation for this. The mathematical constant e is one of the most important numbers in all of mathematics.
