Press = after every equation, for example: three-plus-two-EQUALS-times-eight-EQUALS-squared-EQUALS. IMPORTANT: the back button will get rid of the last number you entered, but also works as a CLEAR button when you finish getting an answer. So, you don't have to press the green flag before a new equation. Press the Square Root , Square, Sin, Cos, or Tan buttons AFTER entering in a number! The "round" button will round an answer currently on the display to the nearest whole number.
This is the much-improved version of my older calculator. Enjoy! If the answer turns red or blue, it means you tried to square-root a negative ;)
