Question: William and Harry played 15 rounds of tic-tac-toe. William won 5 more rounds than Harry. How many rounds did William win?
Answer: Step-by-step reasoning process: They played 15 rounds and William won 5 more rounds than Harry so that leaves 15 - 5 = 10 round. There are 2 players and 10 rounds so they each won 10 / 2 = 5 rounds. William won 5 more rounds than Harry and they each won 5 rounds so William won 5 + 5 = 10 rounds.
So the answer is 10.

Question: Miss Smith is teaching second period English and is shocked at how small the class seems. There are 6 tables in the classroom with 3 students currently sitting at each table. Sally said 3 girls went to the bathroom, and three times more students went to the canteen. Elliott said that 2 groups of students have recently been added to their class, and each group has 4 students in it. None of these students are in the class right now. Lucas pointed out that a few foreign exchange students have joined the class; 3 from Germany, 3 from France, and 3 from Norway. These students are also missing. How many students are supposed to be in the class?
Answer: Step-by-step reasoning process: There are currently 3 * 6 = 18 students sitting in the classroom. There were 3 * 3 = 9 students who went to the canteen. Sally has therefore noticed 3 + 9 = 12 students missing from the class. Elliott said that 2 groups of students have joined the class, so there are another 2 * 4 = 8 students who are not in the classroom. Lucas said that there are 3 + 3 + 3 = 9 foreign exchange students who are not in the classroom. Therefore, there should be 18 + 12 + 8 + 9 = 47 students.
So the answer is 47.
