This guide is exactly for you. We'll go through everything a beginner student needs to know: from the basics, through trigonometry, to solving equations. We'll use the Casio FX-991 series as a reference, as it's the most common in Hungarian secondary schools, but most functions work similarly on other brands.<\/p>\n<p><strong>Tip:<\/strong> If you don't have a physical calculator at hand, <a href=\"\/en\/scientific-calculator-trigonometric-and-special-functions\/\">try our scientific calculator online<\/a> \u2014 with the same functions, right from your browser.<\/p>\n<h2 class=\"wp-block-heading\">What is a scientific calculator and how is it different?<\/h2>\n<p>A scientific calculator (scientific calculator) differs from a regular school calculator in that, beyond basic operations (addition, subtraction, multiplication, division), it also has trigonometric, logarithmic, statistical, and equation-solving functions.<\/p>\n<p><strong>Who should use it?<\/strong><\/p>\n<ul>\n<li>Secondary school students \u2014 for math, physics, chemistry classes and for the final exams<\/li>\n<li>University students \u2014 in engineering, economics, and IT programs<\/li>\n<li>Adult learners \u2014 evening school, online courses, self-study<\/li>\n<\/ul>\n<p>The Casio FX-991CE X is so popular in Hungarian schools because it's reliable, includes all necessary functions, and can be used in final exams.<\/p>\n<h2 class=\"wp-block-heading\">Get to know your calculator<\/h2>\n<p>The first step is to know what each button does. Here are the most important ones:<\/p>\n<ul>\n<li><strong>ON \/ AC<\/strong> \u2014 Power on and clear the display contents<\/li>\n<li><strong>SHIFT<\/strong> \u2014 Access secondary functions (yellow labels above the buttons)<\/li>\n<li><strong>ALPHA<\/strong> \u2014 Tertiary functions (red labels), such as memory variables<\/li>\n<li><strong>MODE<\/strong> \u2014 Switch modes (DEG\/RAD, EQN, STAT, TABLE, etc.)<\/li>\n<li><strong>S\u2194D<\/strong> \u2014 Toggle between fraction and decimal form<\/li>\n<\/ul>\n<p><strong>How to switch modes?<\/strong> Press the MODE button, then select the number of the desired mode. For example, you work in DEG (degree) mode for trigonometry, while in EQN mode you can solve equations.<\/p>\n<h2 class=\"wp-block-heading\">Basic operations and fractions<\/h2>\n<p>The scientific calculator automatically follows the order of operations (parentheses \u2192 powers \u2192 multiplication\/division \u2192 addition\/subtraction). This means that if you enter the expression 3 + 4 \u00d7 2, the result will be 11, not 14. If you want a different order, <strong>use parentheses<\/strong>.<\/p>\n<p><strong>Entering fractions:<\/strong> You can enter fractions with the a b\/c button.
