For one thing, you can choose how many significant figures you want by scrolling to the bottom and entering a number. (The default is 5 significant figures). Numbers from 999,999 to 999,999 will not be in scientific notation but bigger and smaller numbers will be. Here's some examples to familiarize yourself with this calculator. Input 24 into box Number 1 and Input 3 into box Number 2. Clicking "ADD" will give the answer 27. Clicking "SUB" = 21 Clicking "MUL" = 72 Clicking "DIV" = 8 Of these four buttons, the only ones that are just a little tricky are "SUB" and "DIV". For subtraction, it is number 2 being subtracted from number 1. For division, it is number 1 being divided by number 2.
Finally, the "num1^num2" button is a handy tool to have.
