Mary had 89 stickers. She used 3 large stickers on the front page of her journal and 7 stickers each to 6 other pages of her journal. How many stickers does Mary have remaining? Let's think first. Chain of thought:
Mary added a total of 7 stickers / page * 6 pages = 42 stickers to the 6 other pages. In total, Mary added 3 large stickers + 42 stickers = 45 stickers to her journal. Since she started with 89 stickers, she now has 89 - 45 = 44 stickers left.
Therefore, the answer is 44.
