A 5 x 5 grid is supplied. The rows each total the answers at the bottom, the columns each total the answers on the right, and the bottom row, the right-hand column and the diagonal all total the answer in the bottom right-hand corner, which is left blank. Children must place a plus or a minus sign in front of each number to make the rows and columns add up correctly.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Laird Stevens\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 198945402X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781989454022\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Paris Press\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 02\/13\/2019\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 124\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.33lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 8.00h x 5.25w x 0.29d","brand":"Laird Stevens","offers":[{"title":"Paperback","offer_id":48442784973055,"sku":"9781989454022","price":5.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_df07d8a4-f823-4262-b5e8-853aadb84830.jpg?v=1777199754","url":"https:\/\/www.whiterainbookhouse.com\/products\/plus-or-minus-laird-stevens-9781989454022","provider":"WR Book House","version":"1.0","type":"link"}
