The exercises are designed to improve numerical reasoning and trial-and-error problem-solving skills by asking students to manipulate these specific digits to create both the largest and smallest possible sums and differences. The material includes both the challenge tasks and the corresponding answer keys, offering detailed explanations and multiple examples to facilitate self-assessment and conceptual understanding of place value and arithmetic operations. The tasks encourage deep thinking about how digit placement affects the final total or result in complex multi-digit calculations, making it an excellent resource for students seeking to refine their logical approach to mathematics.",{"@graph":69,"@context":122},[70,84,105],{"@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/4-digit-addition-and-subtraction-challenge-3/631314/",{"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/4-digit-addition-and-subtraction-challenge-3/631314.png","ImageObject",300,407,{"name":92,"@type":93},"Lucas Martin","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-10-22",true,{"@type":102,"interactionType":103,"userInteractionCount":24},"InteractionCounter",{"@type":104},"ViewAction",{"@type":106,"mainEntity":107},"FAQPage",[108,114,118],{"name":109,"@type":110,"acceptedAnswer":111},"What is the goal of the 4-digit addition and subtraction challenge?","Question",{"text":112,"@type":113},"The goal is to use the digits 1 through 8 to create the largest or smallest possible answers for addition and subtraction problems, which helps develop trial and improvement skills.","Answer",{"name":115,"@type":110,"acceptedAnswer":116},"How do you form the largest answer for the addition challenge?",{"text":117,"@type":113},"To get the largest answer, place the 8 and 7 in the thousands column, 6 and 5 in the hundreds, 4 and 3 in the tens, and 2 and 1 in the ones place, resulting in 16,173.",{"name":119,"@type":110,"acceptedAnswer":120},"What is the solution for the smallest subtraction challenge?",{"text":121,"@type":113},"The only solution to reach the smallest difference using the digits 1-8 is 5123 - 4876 = 247.","https://schema.org",{"og:url":83,"og:type":124,"og:title":65,"og:site_name":95,"og:description":67},"article",{"robots":126,"canonical":83},"index,follow",{"doc_id":128,"site_id":62},631314,1792900907,{"code":4,"msg":5,"data":131},{"doc_id":128,"user_id":132,"nickname":92,"user_avatar":133,"doc_module":4,"category_id":19,"category_name":20,"doc_title":65,"doc_description":67,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":24,"is_deleted":4,"is_public":8,"is_downloadable":8,"audit_status":8,"page_count":14,"language":139,"language_code":63,"site_id":62,"html_lang":63,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":67,"update_tm":143,"read_time":24},8796095360427,"https://ap-avatar.wpscdn.com/davatar_994ba38a5ba835b3df7d355c54d3ed8d","4-DIGIT ADDITION AND SUBTRACTION CHALLENGE 3  \nWork out the value of the missing digits and write them in.  \n1) Use the digits 1, 2, 3, 4, 5, 6, 7 and 8 each time to make the largest possible answers.  \n +   \n2) Use the digits 1, 2, 3, 4, 5, 6, 7 and 8 each time to make the smallest possible answers.  \n +   \n4-DIGIT ADDITION AND SUBTRACTION CHALLENGE 3 ANSWERS  \n1) Use the digits 1, 2, 3, 4, 5, 6, 7 and 8 each time to make the largest possible answers.  \nFor the addition challenge, any answer where the 8 and 7 are in thousands place, the 6 and 5 are in the hundreds place, the 4 and 3 are in the tens place and the 2 and 1 are in the ones place.
