E notation is also known as exponential notation. E notation is the same as scientific notation where a decimal number between 1 and 10 is multiplied by 10 raised to some power. In E notation the "times 10 raised to a power" is replaced with the letter e in either uppercase or lowercase. The number after the "e" indicates how many powers of 10. In this example calculation we're adding 1.225e5 and 3.655e3: You can think of constants or exact values as having infinitely many significant figures, or at least as many significant figures as the least precise number in your calculation. Use the appropriate number of significant figures when you input exact values in this calculator. In this example you would want to enter 2.00 for the constant value so that it has the same number of significant figures as the radius entry. The resulting answer would be 4.70 which has 3 significant figures.

Most scientific and graphing calculators can only display possibly up to 10 decimal places of accuracy. While this is enough in most instances of everyday use, it can be fairly limiting for applications where higher standards of accuracy are necessary. Hence the existence of big number calculators such as the one above, that can provide far higher levels of accuracy. Big numbers are more likely to be used in fields such as cosmology, astronomy, mathematics, cryptography, and statistical mechanics. You could write down the answer to the first part of the calculation on paper, and enter it into the calculator again. However, it is possible that you may make an error either in writing down the number or in typing it into the calculator. A better method is to use the fact that the calculator retains the last calculated answer, which can then be inserted in the subsequent calculation using the Have you ever wondered how much the earth weighs? Maybe not, but now that you've been asked, you probably do now! Obviously, the earth weighs a lot. The weight of the earth is 6,000,000,000,000,000,000,000,000 kilograms! Whoa! That's a lot of zeros! What if you were working on a problem involving this weight? You certainly wouldn't want to have to punch that number into a calculator over and over again. How time-consuming!
