Here are the combinations:


1%2A3-%284-2%29=1



2%2A3-4%2A1=2



1%2A%284%2B2%29-3=3



2-3%2B4%2B1=4



%284%2A2%29-%283%2A1%29=5



%283%2A4%29%2F%282%2A1%29=6



2%2A%284%2B1%29-3=7



4%2B2%2B3-1=8



3%2A1%2B2%2B4=9



%282%2A3%29%2B%284%2A1%29=10



%282%2A4%29%2B%283%2A1%29=11



3%2B4%2A2%2B1=12



3%2A%281%2B2%29%2B4=13



2%2A1%2A%284%2B3%29=14



2%2A%284%2B3%29%2B1=15
