As a rough estimate, you can say the product (result of multiplication) is about 4 times 8, or

As a closer estimate, you can say it is about

(3 1/2)*(8 1/2) ≈ 3*8 + (1/2)*(3+8) =

The actual product of these numbers is 30 1/4.

The difference of these numbers, which is what the given expression appears to represent, is -4 7/12. Using the above approximations of the numbers involved, the difference might be estimated as -4 or -5.

**32**.As a closer estimate, you can say it is about
