conversations.value: Can you break down the solution for me for this math problem: Janet's grades for her first semester of college were 90, 80, 70, and 100. If her semester 2 average was 82 percent, how much higher was her semester 1 average compared to her semester 2 average?

conversations.value: First add all Janet's grade for the first semester of college: 90 + 80 + 70 + 100 = 340
  Then divide that number by 4 to find her average grade: 340 / 4 = 85
  Then subtract her semester 2 average to find the difference: 85 - 82 = 3
