Human: Mary had 6 lambs and 2 of the lambs had 2 babies each. She traded 3 lambs for one goat. One morning, she woke up and found an extra 7 lambs in the field. How many lambs does Mary have? Assistant: 
How many lambs did Mary's 2 lambs have? ** 2 of her lambs had 2 babies each so that adds 2*2 = <<2*2=4>>4 lambs
How many lambs did Mary have? ** She starts with 6 and adds 4 baby lambs so she had 6+4 = <<6+4=10>>10 lambs
How many lambs does Mary have? ** She traded 3 of those lambs for a goat so she has 10-3 =<<10-3=7>>7 lambs
How many lambs does Mary have? ** She has 7 and woke up to find 7 more lambs in the field so she has a total of 7+7 = <<7+7=14>>14 lambs
