Expressing Large Numbers on a Calculator or Exponent via EE button
E (or e) stands for exponent of 10, and it’s always followed by another number, which is the value of the exponent. For example, a calculator would show the number 26 trillion as either 2.6E13 or 2.6e13.
Another example, the mass of the earth is 5,970,000,000,000,000,000,000,000 kilograms, and the mass of a hydrogen atom is 0.00000000000000000000000000167 kilograms.
The mass of the earth would be shown as 5.97E24 (or 5.97e24) on a calculator. The number 5.97 is the argument and the number 24 is the exponent. Similarly, the mass of a hydrogen atom would be 1.67E-27 (or 1.67e-27).
Entering Scientific Notation on the Calculator Keypad
Calculators EE key is used to enter a number in scientific notation. Input the argument, then press the EE key and enter the exponent. For example, to enter the mass of the earth, key in 5.97, then press the EE key and enter 24. The display will read 5.97E24 (or 5.97e24). The number appears with all its zeroes if they fit on the screen. For example, if you key in 1.3 EE 5, the display will show 130,000.
