17.951 Special Graduate Topic in Political Science: Public Opinion (MIT)
This course provides an introduction to the vast literature devoted to public opinion. In the next 12 weeks, we will survey the major theoretical approaches and empirical research in the field of political behavior (though we will only tangentially discuss political  participation and voting). For the most part we will focus on American public opinion, though some of the work we will read is comparative in nature.

Lastly consider division. Dividing 8 by 2 means â€˜How many times does 2 go into 8?â€™ or â€˜What must you multiply 2 by to get 8?â€™. The answer is 4.

So to find 8 Ã· âˆ’2, you need to ask â€˜What do I have to multiply âˆ’2 by to get 8?â€™. The answer is âˆ’4, since âˆ’2 Ã— âˆ’4 = 8.

So 8 Ã· âˆ’2 = âˆ’4.

Similarly, to find âˆ’8 Ã· âˆ’2 you need to ask â€˜what do I have to mul

## Activity 6

What is 370.76 grams in kilograms? There are 1000 grams in a kilogram.

370.76 Ã· 1000 = 0.370 76.

So 370.76 g = 0.370
