How To Solve Billion Problems Using Calculator?
If you solve a billion problems on your calculator, both your fingers and the calculator are likely to be completely worn out. Even the best mechanical switches are usually worn out after 10 million operations. (Lol) Some calculators won’t display a billion, except in scientific notation, as they have only 8 digits or less. Depending on where you live, a billion is either 109 or 1012. You can enter that sort of number using the key that lets you enter an exponent. On my favorite calculator, that key is marked “E”. On another calculator I have, the key is marked “EEX” (enter exponent).
