I'm guessing you have to make a table of x and y values, and one of your x values is 1, that is why it is in parenthesis?

Any time you have fractions and whole numbesr turn the whole numbers into fractions by putting a 1 under them. And remember that whenever you have a number next to a number in parenthesis it means multiply.

3 x 1 - 3

2 1 1

Multiplication comes before subtraction

3 x 1 = 3

2 1 2

Now subtract

3 - 3 = ? You have to have common denominators to add or sub

Nicole did a terrific job of describing how you multiply a fraction and a whole number. :-) I only have one comment to add.

ANY number or variable multiplied by 1 is itself. That is true regardless of what kind of number it is. so, using a * to mean multiplication (that's what computers use) :

5 * 1 = 5

1/2 * 1 = 1/2

99/852 * 1 = 99/852

Q * 1 = Q

(orangutan) * 1 = (orangutan) ... and so on.

So if you are multiplying a fraction ... by one... you do not have to go through the multiplication process, you just know it is itself. In your example, (3/2)(1) simply is 3/2... then you subtract 3 from that. Nicole has explained the fraction and negative number math beautifully.
