There are 29 students in a classroom with 7 tables. If 4 students can sit at a table, how many students cannot sit down at tables?

Answer 1

There are a total of 7 tables in the classroom, each seating 4 students, so the total number of students that can sit at the tables is 7 tables * 4 students per table = <<7*4=28>>28 students.
Therefore, the number of students that cannot sit down at the tables is 29 students - 28 students = <<29-28=1>>1 student. Answer: \boxed{1}.
