<human>:  Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era?
<bot>: How many halves are made? ** There are 5 x 1/2 = 10 halves of burgers made from 5 whole burgers.
How many slices did Era's first and second friends get together? ** Era's first and second friends got 1 + 2 = <<1+2=3>>3 slices together.
How many slices did Era's third and fourth friends get together? ** Her third and fourth friends got 3 + 3 = <<3+3=6>>6 slices together.
How many slices did Era's four friends get together? ** Era's four friends got 3 + 6 = <<3+6=9>>9 slices.
How many slices are left for Era? ** So, Era is left with 10 - 9 = <<10-9=1>>1 slice.
