Answer :

Sure, let's break down the multiplication of 89 and 55 step-by-step:

1. Write the numbers one below the other, aligning the digits by place value:
```
89
x 55
------
```

2. Multiply the bottom number (55) by the top number (89) starting from the rightmost digit:
- First, we multiply 89 by 5:
```
89
x 5
------
445 (This is 89 5)
```

- Second, multiply 89 by the next digit in 55, which is also 5. But remember, since we're dealing with the tens place, we add a zero to the end of this product:
```
89
x 50
------
4450 (This is 89
50)
```

3. Now, add up these two results:
```
445
4450
------
4895
```

So, the product of 89 and 55 is 4895.
