Multiply 83 by 87.

Answer

To multiply 83 by 87, we can use the traditional multiplication method. Here’s a step-by-step breakdown:

### Step 1: Write the numbers
Write the numbers vertically, aligning them by place value:
```
83
× 87
```

### Step 2: Multiply the units place
Start by multiplying the units place of the second number (7) by the first number (83):
- \(7 \times 3 = 21\) (write down 1 and carry over 2)
- \(7 \times 8 = 56\) (add the carry over 2: \(56 + 2 = 58\))

So, the first row of the answer is:
```
581
```

### Step 3: Multiply the tens place
Next, multiply the tens place of the second number (8) by the first number (83). Remember to add a zero since we are now multiplying by the tens place:
- \(8 \times 3 = 24\) (write down 4 and carry over 2)
- \(8 \times 8 = 64\) (add the carry over 2: \(64 + 2 = 66\))

So, the second row of the answer is:
```
6640
```
(Note: The zero is added because we are in the tens place.)

### Step 4: Add the results
Now, we add the two results together:
```
581
+ 6640
------
7221
```

Thus, the final answer is:
**83 multiplied by 87 equals 7221.**
