He has a table which initially has  rows and  columns. He then adds  extra rows to it. How many total cells does he have finally?

### Input Format

The only line in the input contains three space-separated integers , and  — the number of initial rows, the number of columns, and the number of extra rows added, respectively.

### Output Format

Output on a new line, a single integer, which should be the final total number of cells in the table.

• 1≤�≤100
• 1≤�≤100
• 1≤�≤100

Input

Output

5 2 1

12


### Explanation:

There are initially 5 rows, and 2 columns. So the initial number of cells was 5∗2=10. Then, 1 extra row was added. So now the table has 6 rows, and 2 columns. So the total number of cells is now 6∗2=12, which is the answer.

### Sample 2:

Input

Output

6 10 3

90


### Explanation:

There are initially 6 rows, and 10 columns. So the initial number of cells was 6∗10=60. Then, 3 extra rows were added. So now the table has 9 rows, and 10 columns. So the total number of cells is now 9∗10=90, which is the answer.

### Sample 3:

Input

Output

1 1 1

2


### Explanation:

There are initially 1 rows, and 1 columns. So the initial number of cells was 1∗1=1. Then, 1 extra row was added. So now the table has 2 rows, and 1 columns. So the total number of cells is now 2∗1=2, which is the answer.

### Sample 4:

Input

Output

100 100 100

20000


### Explanation:

There are initially 100 rows, and 100 columns. So the initial number of cells was 100∗100=10000. Then, 100 extra rows were added. So now the table has 200 rows, and 100 columns. So the total number of cells is now 200∗100=20000, which is the answer.
