The document is structured into four distinct parts, starting with simple one-variable, one-operation problems and progressing to more complex scenarios involving two operations, parentheses, and multiple variables. Each section requires students to substitute given values for variables and apply the correct order of operations. The worksheet also features a bonus challenge for advanced practice and concludes with a complete answer key for self-assessment, making it an excellent resource for K-12 mathematics classrooms and independent study. The content is designed to reinforce foundational algebraic concepts through structured, step-by-step problem-solving.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/evaluating-expressions-with-variables-math-practice-worksheet/359055/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/evaluating-expressions-with-variables-math-practice-worksheet/359055.png","ImageObject",300,407,{"name":92,"@type":93},"Rhys","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-11-07","2026-09-23",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",11,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"How should a student approach evaluating an expression with variables?","Question",{"text":113,"@type":114},"A student should first substitute the given numerical value for the variable in the expression and then follow the standard order of operations to solve it.","Answer",{"name":116,"@type":111,"acceptedAnswer":117},"What is the purpose of the provided answer key?",{"text":118,"@type":114},"The answer key allows students or instructors to verify the correctness of the calculations for all sixteen practice problems and the final bonus challenge.",{"name":120,"@type":111,"acceptedAnswer":121},"What topics are covered in the worksheet?",{"text":122,"@type":114},"The worksheet covers substituting variables in expressions, handling parentheses, performing multiple mathematical operations, and solving problems with two different variables.","https://schema.org",{"og:url":83,"og:type":125,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":127,"canonical":83},"index,follow",{"doc_id":129,"site_id":62},359055,1790389490,{"code":4,"msg":5,"data":132},{"doc_id":129,"user_id":133,"nickname":92,"user_avatar":134,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":135,"file_id":136,"file_url":137,"file_type":138,"file_size":139,"view_count":105,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":81,"language":140,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":141,"faqs":142,"seo_title":143,"seo_description":67,"update_tm":144,"read_time":39,"preview_page_count":4},687207024643,"https://ap-avatar.wpscdn.com/davatar_3d24733baf745e90a7e4bdd5f77d97b2","Name:  \n_________________________________________  \nEvaluating Expressions with Variables  \nDirections: Substitute the given value(s) for the variable(s) and evaluate each expression.
