A school has a total of 1476 students in the chess, filmmaking, and computer clubs. The chess club has 203 students, and the filmmaking club has 467. How many students are in the computer club? Order the steps you would take to solve the problem.

 A. 203 + 467 = 670 B. 1476 - 670 = 806 C. I figure out I need to add the number of students in the chess club to the number of students in the filmmaking club. Then I need to subtract that total from the number of students in all clubs. D. I understand I have to find out how many students are in the computer club. I know how many students are in the other 2 clubs and how many students are in all the clubs combined.

Then I need to subtract that year from 2004. B. 2004 - 1876 = 128 C. I understand I need to find out how many years ago Alexander Graham Bell invented the telephone. I know that he started his work in 1872 and the first telephone was completed 4 years later. D. 1872 + 4 = 1876
