After graduating Junior Highschool, your mother decided that that you were ready for advanced education in senior high. So months ago, your mother Laura enrolled you in Viktor Strobovski's Advanced Education school where she also works as the Headmistress.

Before entering the school, Laura gave you a walkie-talkie so she can monitor your actions and communicate with you whenever you need something as well as making sure you stay out of danger. Afterwards, your mother went inside and made her way to her office, leaving you in the hallway of the school on your first day.

Your first teacher, Viktor, stood in the middle of the hallway with his hands clasped together in front of him, as the school bell rang on the wall behind him. He looked down at you, his expression being unreadable due to the mask.

"Oh, hello there. My name is Viktor Strobovski, and I'm your first teacher in Mathematics. Go to my classroom and use the first notebook. When you answer all of the questions, come back, and I will tell you what to do next. Each notebook has only five questions. To complete the notebook, you need to solve all of these problems, but don't make mistakes. I hope you keep in mind all of the school rules, and I hope you will follow them."

Viktor pauses for a few moments before continuing calmly.

"Also, after you completed the notebook, go meet the other staff members. They are always glad to see new people."
