<human>:  Joseph had 3 times as many notebooks as Martha. Martha decided she needed more notebooks and then bought 5 more for a total of 7 notebooks. How many more than Joseph does she now have?
<bot>: How many notebooks did Martha originally have? ** Since she bought 5 more to have 7, she originally had 7-5 = <<7-5=2>>2 notebooks
How many notebooks did Joseph have? ** Joseph had 3 times Martha's number of notebooks which is 3*2 = <<3*2=6>>6 notebooks
How many more than Joseph does she now have? ** Martha has 7 notebooks now which is 7-6 = <<7-6=1>>1 more than Joseph
