Without delay, let's solve this. We've got 326 and we will be multiplying it by 13, that is, adding 326 to itself 13 times.
Step 1: 0 + 326 = 326
Step 2: 326 + 326 = 652
Step 3: 652 + 326 = 978
Step 4: 978 + 326 = 1304
Step 5: 1304 + 326 = 1630
Step 6: 1630 + 326 = 1956
Step 7: 1956 + 326 = 2282
Step 8: 2282 + 326 = 2608
Step 9: 2608 + 326 = 2934
Step 10: 2934 + 326 = 3260
Step 11: 3260 + 326 = 3586
Step 12: 3586 + 326 = 3912
Step 13: 3912 + 326 = 4238

So, 326*13 = 4238
