Find the Equal Sign on a Graphing Calculator

A graphing calculator helps students understand the relationship between mathematics and science. A graphing calculator is used in classes like algebra, trigonometry, calculus, physics and statistics. The calculator helps students visualize problems by entering formulas and complex equations that a regular calculator cannot do. A graphing calculator features more buttons and options than a regular calculator, so finding the "equal" sign can be difficult. Depending on what type of graphing calculator you are using, finding the "equal" sign requires you to push a series of buttons.
