multiplication problems, times then add

all of these should have three ways of obtaining the result

later questions ask students to find a set of 5 numbers (different to those earlier)
a result of 17 has many sets of five numbers, one set giving 4 ways to obtain the result

a result of 23 also has many sets of five numbers
