OK, let's work through this together. We're starting with 918 and we're going to multiply it by 26, which means we add 918 to itself 26 times.
Step 1: 0 + 918 = 918
Step 2: 918 + 918 = 1836
Step 3: 1836 + 918 = 2754
Step 4: 2754 + 918 = 3672
Step 5: 3672 + 918 = 4590
Step 6: 4590 + 918 = 5508
Step 7: 5508 + 918 = 6426
Step 8: 6426 + 918 = 7344
Step 9: 7344 + 918 = 8262
Step 10: 8262 + 918 = 9180
Step 11: 9180 + 918 = 10098
Step 12: 10098 + 918 = 11016
Step 13: 11016 + 918 = 11934
Step 14: 11934 + 918 = 12852
Step 15: 12852 + 918 = 13770
Step 16: 13770 + 918 = 14688
Step 17: 14688 + 918 = 15606
Step 18: 15606 + 918 = 16524
Step 19: 16524 + 918 = 17442
Step 20: 17442 + 918 = 18360
Step 21: 18360 + 918 = 19278
Step 22: 19278 + 918 = 20196
Step 23: 20196 + 918 = 21114
Step 24: 21114 + 918 = 22032
Step 25: 22032 + 918 = 22950
Step 26: 22950 + 918 = 23868

So, 918*26 = 23868
