<human>:  Christopher, Jameson, and June each bought a toy sword. June's sword is 5 inches longer than Jameson's sword. Jameson's sword is 3 inches longer than twice the length of Christopher's sword. Christopher's sword is 15 inches long. How many inches longer is June's sword than Christopher's sword?
<bot>: How long is twice the length of Christopher's sword? ** Twice the length of Christopher's sword is 15 x 2 = <<15*2=30>>30 inches.
How long is Jameson's sword? ** So, Jameson's sword is 30 + 3 = <<30+3=33>>33 inches long.
How long is June's sword? ** June's sword is 33 + 5 = <<33+5=38>>38 inches long.
How many inches longer is June's sword than Christopher's sword? ** Thus, June's sword is 38 - 15 = <<38-15=23>>23 inches longer than Christopher's sword.
