OK, let's work through this together. We're starting with 163 and we're going to multiply it by 26, which means we add 163 to itself 26 times.
Step 1: 0 + 163 = 163
Step 2: 163 + 163 = 326
Step 3: 326 + 163 = 489
Step 4: 489 + 163 = 652
Step 5: 652 + 163 = 815
Step 6: 815 + 163 = 978
Step 7: 978 + 163 = 1141
Step 8: 1141 + 163 = 1304
Step 9: 1304 + 163 = 1467
Step 10: 1467 + 163 = 1630
Step 11: 1630 + 163 = 1793
Step 12: 1793 + 163 = 1956
Step 13: 1956 + 163 = 2119
Step 14: 2119 + 163 = 2282
Step 15: 2282 + 163 = 2445
Step 16: 2445 + 163 = 2608
Step 17: 2608 + 163 = 2771
Step 18: 2771 + 163 = 2934
Step 19: 2934 + 163 = 3097
Step 20: 3097 + 163 = 3260
Step 21: 3260 + 163 = 3423
Step 22: 3423 + 163 = 3586
Step 23: 3586 + 163 = 3749
Step 24: 3749 + 163 = 3912
Step 25: 3912 + 163 = 4075
Step 26: 4075 + 163 = 4238

So, 163*26 = 4238
