Let's get this math done. We have 245 and we're going to multiply it by 13. This is the same as taking 245 and adding it to itself 13 times.
Step 1: 0 + 245 = 245
Step 2: 245 + 245 = 490
Step 3: 490 + 245 = 735
Step 4: 735 + 245 = 980
Step 5: 980 + 245 = 1225
Step 6: 1225 + 245 = 1470
Step 7: 1470 + 245 = 1715
Step 8: 1715 + 245 = 1960
Step 9: 1960 + 245 = 2205
Step 10: 2205 + 245 = 2450
Step 11: 2450 + 245 = 2695
Step 12: 2695 + 245 = 2940
Step 13: 2940 + 245 = 3185

So, 245*13 = 3185
