Answer 1

To multiply 45 by 81 by hand, you can use the standard multiplication method. Here's how it works step-by-step:

1. Write the numbers vertically, aligning them by the right:

   45
×  81
____

2. Multiply the bottom number (1) by the top number (45):

   45
×  81
____
   45   (1 * 45)

3. Now, multiply the bottom number (8) by the top number (45). Since the 8 is in the tens place, we add a zero to the right:

   45
×  81
____
   45   (1 * 45)
+360   (8 * 45, shifted one position to the left)
____

4. Now, add the two results together:

   45
+360
____
  3645

So, \( 45 \times 81 = 3645 \).

Therefore, the answer is 3,645.
