# 3.3.5 Performing Multiplication and Division

## Activity: Multiplication and Division

In your math notebook, perform the following operations by hand.

(a)

### Discussion

For multiplication, begin by writing the problem vertically and lining up the digits in the units place. For division, set the problem up using for the division symbol.

(a)

Thus, the answer is 12,876. (This seems reasonable since .)

(b)

(b)

Thus, the answer is 12,880. (This seems reasonable since.)

(c)

(c)

So the solution is 207. (This seems reasonable because .)

(d)

(d)

So the solution is 269.
