If Antonia is trying to organize her class of 20 students into rows for the class photo and each row is to have equal number of students. What possible arrangements can he have?
She can have 10 rows of 2, 4 rows of 5 students, 5 rows of 4 students, or one row of 20 students.
Place parentheses to make this true:
17 - 8 x 2 + 6 x 11 - 5 = 37
17 - 8 x 2 + 6 x (11 - 5) = 37
