Let's roll up our sleeves and solve this. We have 860 and we're going to multiply it by 26, essentially adding 860 to itself 26 times.
Step 1: 0 + 860 = 860
Step 2: 860 + 860 = 1720
Step 3: 1720 + 860 = 2580
Step 4: 2580 + 860 = 3440
Step 5: 3440 + 860 = 4300
Step 6: 4300 + 860 = 5160
Step 7: 5160 + 860 = 6020
Step 8: 6020 + 860 = 6880
Step 9: 6880 + 860 = 7740
Step 10: 7740 + 860 = 8600
Step 11: 8600 + 860 = 9460
Step 12: 9460 + 860 = 10320
Step 13: 10320 + 860 = 11180
Step 14: 11180 + 860 = 12040
Step 15: 12040 + 860 = 12900
Step 16: 12900 + 860 = 13760
Step 17: 13760 + 860 = 14620
Step 18: 14620 + 860 = 15480
Step 19: 15480 + 860 = 16340
Step 20: 16340 + 860 = 17200
Step 21: 17200 + 860 = 18060
Step 22: 18060 + 860 = 18920
Step 23: 18920 + 860 = 19780
Step 24: 19780 + 860 = 20640
Step 25: 20640 + 860 = 21500
Step 26: 21500 + 860 = 22360

So, 860*26 = 22360
