Multiply 734 by 99.

Answer

To multiply 734 by 99, we can follow these steps:

### Step 1: Write the numbers
We start by writing the numbers we want to multiply:
```
734
× 99
```

### Step 2: Multiply the first digit of the second number (9) by the first number (734)
We multiply 734 by 9:
- \(9 \times 4 = 36\) (write 6 and carry over 3)
- \(9 \times 3 = 27\), plus the carry over 3 gives \(27 + 3 = 30\) (write 0 and carry over 3)
- \(9 \times 7 = 63\), plus the carry over 3 gives \(63 + 3 = 66\)

So, the first row of the multiplication is:
```
734
× 99
______
6606 (This is 734 × 9)
```

### Step 3: Multiply the second digit of the second number (9) by the first number (734)
Now we multiply 734 by the second 9 (which is actually in the tens place, so we will add a zero):
- \(9 \times 4 = 36\) (write 6 and carry over 3)
- \(9 \times 3 = 27\), plus the carry over 3 gives \(27 + 3 = 30\) (write 0 and carry over 3)
- \(9 \times 7 = 63\), plus the carry over 3 gives \(63 + 3 = 66\)

So, the second row of the multiplication is:
```
734
× 99
______
6606 (This is 734 × 9)
+66060 (This is 734 × 90)
```

### Step 4: Add the two results together
Now we add the two results:
```
6606
+66060
______
72666
```

Thus, the final answer is:
**734 × 99 = 72666**
