conversations.value: Provide a step by step solution for the following math problem: Shawna's workout goal is 30 situps. On Monday, Shawna was only able to do 12 situps, so she decided that she would make up for the rest on Tuesday. However, she was only able to do 19 situps on Tuesday. How many situps would Shawna have to do on Wednesday to meet her minimum goal and make up for the ones she didn't do?

conversations.value: On Monday, Shawna was short of 30 - 12 = 18 situps
  On Tuesday, Shawna was short of 30 - 19 = 11 situps
  On Wednesday, Shawna would have to do 30 + 18 + 11 = 59 situps
