You can type directly or use the keypad. For example, enter <code>sqrt(49) + 3^2<\/code> to add a square root and a power.<\/li>\n<li>Check the <strong>DEG<\/strong> or <strong>RAD<\/strong> button before using trigonometric functions. Click it to switch modes. DEG treats an angle such as <code>30<\/code> as degrees; RAD treats it as radians.<\/li>\n<li>Press <strong>=<\/strong> or Enter to evaluate the expression. Read the answer beside <strong>Result<\/strong>. To use that answer in another calculation, insert <strong>Ans<\/strong> into the expression.<\/li>\n<li>Use <strong>\u232b<\/strong> to delete a character or selected text, or <strong>C<\/strong> to clear the expression. Successful calculations appear under <strong>Recent calculations<\/strong>, with the angle mode used for each one.<\/li>\n<\/ol>\n<h2>Understanding scientific expressions<\/h2>\n<p>A scientific calculator combines ordinary arithmetic with functions such as sine, square root and logarithm. Enter an entire expression instead of calculating each part separately. Multiplication and division are evaluated before addition and subtraction; powers are evaluated before multiplication. Parentheses let you control the grouping. For instance, <code>(2 + 3)^2<\/code> gives 25, while <code>2 + 3^2<\/code> gives 11.<\/p>\n<p>Functions take an argument in parentheses: write <code>sin(30)<\/code>, <code>sqrt(49)<\/code>, <code>ln(e)<\/code> or <code>log10(100)<\/code>. The calculator supports <code>sin<\/code>, <code>cos<\/code>, <code>tan<\/code> and their inverse functions <code>asin<\/code>, <code>acos<\/code> and <code>atan<\/code>. The inverse trigonometric functions return angles in the selected mode. Choose the mode based on your problem, not on the size of the number entered. For more work with angles and side lengths, use the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/trigonometry-calculator\/\">Trigonometry Calculator<\/a>.<\/p>\n<p>The result is a numerical value, not an automatic unit conversion. If your expression adds lengths measured in metres, interpret the result in metres; if it combines quantities with different units, check that the operation is meaningful. The displayed result may be rounded, so it can differ slightly from an exact value involving \\(\\pi\\), roots or trigonometric functions.<\/p>\n<h2>Syntax, limits and practical tips<\/h2>\n<ul>\n<li>Use <code>^<\/code> for powers, <code>sqrt(...)<\/code> for square roots, <code>\u03c0<\/code> or <code>pi<\/code> for pi, and <code>e<\/code> for Euler\u2019s number. The keypad\u2019s <strong>x\u00b2<\/strong> and <strong>1\/x<\/strong> keys insert a square and a reciprocal power, respectively.<\/li>\n<li><strong>EXP<\/strong> inserts <code>E<\/code> for scientific notation. For example, <code>2E3<\/code> means \\(2\\times10^3=2000\\). To convert numbers between notation formats, use the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/scientific-notation-calculator\/\">Scientific Notation Calculator<\/a>.<\/li>\n<li><code>%<\/code> divides the value immediately before it by 100. Thus <code>200*10%<\/code> gives 20, but <code>200+10%<\/code> gives 200.1; it does not add 10% of 200.<\/li>\n<li>The <strong>n!<\/strong> key inserts <code>!<\/strong> after a value. Factorials require a non-negative integer and are limited to <code>170!<\/code>. For a dedicated factorial calculation, see the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/factorial-calculator\/\">Factorial Calculator<\/a>.<\/li>\n<li>Square roots of negative numbers, logarithms of zero or negative numbers, division by zero, and undefined tangent angles produce an error rather than a real-number result. Check the input and angle mode if an error appears. For more detail on logarithm bases and values, use the <a href=\"https:\/\/wpcalc.com\/en\/mathematics\/logarithm-calculator\/\">Logarithm Calculator<\/a>.<\/li>\n<\/ul>\n<p>Results are displayed to about 12 significant digits, which is suitable for routine numerical work but not a substitute for exact symbolic algebra. <strong>Ans<\/strong> refers to the last successful calculation; an error does not replace it. Recent history lists up to 10 successful calculations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evaluate arithmetic, powers, roots, trigonometric functions, logarithms and factorials.
