Delete clones himself with each sneeze, and he sneezes 103 times. Lucky claims that it will take too long to use addition to calculate the number of clones he has created. Inez creates another table and suggests they start with a multiple that is close to 103. The group uses her strategy to quickly determine that Delete has created 309 clones of himself.
Inez and Lucky try to determine how many clones exist of Delete. They write down what they know and notice a pattern: every time Delete sneezes, three new clones appear. Inez then explains how they can calculate the number of Delete clones that exist using multiplication.
Jackie couldn't count all of Delete's clones when they passed by her, so Inez and Lucky calculate the number of clones based on sneezes. Since Delete sneezed 13 times, and each sneeze creates 3 new clones, Delete has 39 clones in total. Lucky isn't convinced, so Inez walks her through the calculation, explaining that multiplication is the same as repeating addition.
