What does the 3 mean? It is called a <strong>coefficient<\/strong>. A coefficient is a number that multiplies a variable. In this guide, you will learn what a coefficient in math is, how to find one, and how to tell it apart from a constant.

A variable is a letter, such as x or y, that stands for a number.<\/p>\n\n\n\n<p>For example:<\/p>\n\n\n\n<p><code>4x<\/code><\/p>\n\n\n\n<p>The number 4 is the coefficient of x. It means <strong>4 \u00d7 x<\/strong>.<\/p>\n\n\n\n<p>If x equals 3, then:<\/p>\n\n\n\n<p><code>4 \u00d7 3 = 12<\/code><\/p>\n\n\n\n<p>So, <code>4x = 12<\/code>.<\/p>\n\n\n\n<p>You can think of a coefficient as the number of groups of a variable.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Simple examples of coefficients<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Math Term<\/td><td>Coefficient<\/td><td>Variable<\/td><\/tr><tr><td>2x<\/td><td>2<\/td><td>x<\/td><\/tr><tr><td>5y<\/td><td>5<\/td><td>y<\/td><\/tr><tr><td>8a<\/td><td>8<\/td><td>a<\/td><\/tr><tr><td>10b<\/td><td>10<\/td><td>b<\/td><\/tr><tr><td>6m<\/td><td>6<\/td><td>m<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">What if there is no number?<\/h3>\n\n\n\n<p>Sometimes, the coefficient is not written.

For example, in <code>5x<\/code>, the coefficient is 5. It means five times x. In <code>-3y<\/code>, the coefficient is -3. When a variable stands alone, its coefficient is 1. For example, <code>x<\/code> means <code>1x<\/code>. Learning coefficients helps students understand algebra expressions.<\/p>\n\n\n\n<ol start=\"2\" class=\"wp-block-list\">\n<li>How do you find a coefficient?<\/li>\n<\/ol>\n\n\n\n<p>First, find the variable in the expression. Then look for the number multiplying it. Remember to include the minus sign if there is one. For example, in <code>-7x<\/code>, the coefficient is -7. In <code>4y + 2<\/code>, the coefficient of y is 4, and 2 is the constant.<\/p>\n\n\n\n<ol start=\"3\" class=\"wp-block-list\">\n<li>Is the coefficient always a whole number?<\/li>\n<\/ol>\n\n\n\n<p>No. A coefficient can be a whole number, negative number, fraction, or decimal. For example, the coefficient of <code>\u00bdx<\/code> is \u00bd, and the coefficient of <code>0.5y<\/code> is 0.5. A variable can also have a hidden coefficient of 1, as in <code>x<\/code>.<\/p>\n<div class=\"retention-card-new\" data-lang=\"en\" data-subject=\"CHINESE\" data-btnName=\"Get started free!\" data-subTitle=\"Specially tailored for kids aged 3-18 around the world!\">\r\n    <div class=\"retention-card-l\">\r\n        <div class=\"trustpilot-image\">\r\n            <!-- TrustBox widget - Micro Star -->\r\n            <div class=\"trustpilot-widget\" data-locale=\"en-US\" data-template-id=\"5419b732fbfb950b10de65e5\" data-businessunit-id=\"60c847b7f033d300019ff3a1\" data-style-height=\"24px\" data-style-width=\"272px\" data-token=\"7dc9fdab-8926-4826-ad90-81ab38cc0953\">\r\n              <a href=\"https:\/\/www.trustpilot.com\/review\/wukongsch.com\" target=\"_blank\" rel=\"noopener\">Trustpilot<\/a>\r\n            <\/div>\r\n            <!-- End TrustBox widget -->\r\n        <\/div>\r\n        <h3><p>Learn <span>authentic Chinese<\/span> from those who live and breathe the culture.<\/p>\n<\/h3>\r\n        <p>Specially tailored for kids aged 3-18 around the world!<\/p>\r\n        <a class=\"retention-card-button is-point\" href=\"https:\/\/www.wukongsch.com\/independent-appointment\/?subject=chinese&amp;l=d232a08b-51de-4a90-b301-47ad0f87f71a&amp;booking_triggerevent=BLOG_DETAIL_MODEL_CTA_BUTTON\" data-buttonname=\"\u7acb\u5373\u9884\u7ea6\u6309\u94ae\u70b9\u51fb\" data-event=\"C_Blog_BLOG_DETAIL_MIDDLE_CTA_BUTTON\" data-expose-buttonname=\"\u7acb\u5373\u9884\u7ea6\u6309\u94ae\u66dd\u5149\" data-expose-event=\"D_Blog_BLOG_DETAIL_MIDDLE_CTA_BUTTON\" target=\"_blank\" title=\"Get started free!\">\r\n            Get started free!\r\n        <\/a>\r\n    <\/div>\r\n    <div class=\"retention-card-r\"><\/div>\r\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Have you seen a problem like 3x + 5 in your math homework?
