Our calculators are trying to display the number using scientific notation. My calculator would use the capital E instead of the lower case e. Scientific notation shows a number with a decimal, a fractional decimal portion times 10 raised to an exponent.
So just adjust your decimal point, to the right for positive numbers and left for negative numbers. This notation is what we lived with when we used real slide rules. So, in the example given,. If you want to write this number in normal number form, just move the invisible decimal point to the right, adding zeroes as necessary. That is a form to write Scientific notation of numbers. The calculator is telling you that the full number is 5.
A simple way of realizing this answer is to move the decimal place to the right by 15 numbers. If the answer were 5. Science is full of very large and very small numbers that are difficult to read and write. For example, the mass of the earth is 5,,,,,,,, kilograms, while the mass of a hydrogen atom is 0. Scientific notation makes these numbers easier to handle by expressing the 0's as a power of ten. Using this notation, the mass of the Earth becomes 5.
Instead of numbers with long strings of zeros that are difficult to count and even more difficult to display on a small screen, you have more manageable decimal fractions and exponents of In its written form, scientific notation would look strange on a calculator.
It would be confusing and it wouldn't fit on a small display. To avoid these problems, manufacturers created a symbol for "X This letter is always followed by a number, which is the exponent to which 10 is raised.
