Answer 1

To solve the multiplication of 13 and 17 using the standard method, we can follow these steps:

1. Multiply 13 by 7 (the units digit of 17): \[ 13 \times 7 = 91 \] We write 91 below the line.

2. Multiply 13 by 1 (the tens digit of 17) and shift it one place to the left (which is the same as multiplying by 10): \[ 13 \times 1 = 13 \quad \text{(this represents 130)} \] We write this below the 91, shifted one position to the left.

Now we have:

   13
x  17
------
   91   (13 x 7)
+130   (13 x 1, shifted one position)
------

3. Add the two results together: \[ 91 + 130 = 221 \]

So the multiplication looks like this:

   13
x  17
------
   91
+130
------
  221

The final answer is:

   221
