Human: There are 14 caterpillars on the tree. 4 more eggs hatch, and baby caterpillars climb out to munch on the leaves. 8 fat caterpillars leave the tree to cocoon themselves to be butterflies. How many caterpillars are left on the tree? Assistant: 
How many caterpillars are there? ** With the new babies, there are 14 + 4 = <<14+4=18>>18 caterpillars.
How many caterpillars are left on the tree? ** With the big caterpillars leaving, there are 18 - 8 = <<18-8=10>>10 caterpillars on the tree.
