OK, let's crack this. We're given 228 and our task is to multiply it by 31. Essentially, we'll be adding 228 to itself 31 times.
Step 1: 0 + 228 = 228
Step 2: 228 + 228 = 456
Step 3: 456 + 228 = 684
Step 4: 684 + 228 = 912
Step 5: 912 + 228 = 1140
Step 6: 1140 + 228 = 1368
Step 7: 1368 + 228 = 1596
Step 8: 1596 + 228 = 1824
Step 9: 1824 + 228 = 2052
Step 10: 2052 + 228 = 2280
Step 11: 2280 + 228 = 2508
Step 12: 2508 + 228 = 2736
Step 13: 2736 + 228 = 2964
Step 14: 2964 + 228 = 3192
Step 15: 3192 + 228 = 3420
Step 16: 3420 + 228 = 3648
Step 17: 3648 + 228 = 3876
Step 18: 3876 + 228 = 4104
Step 19: 4104 + 228 = 4332
Step 20: 4332 + 228 = 4560
Step 21: 4560 + 228 = 4788
Step 22: 4788 + 228 = 5016
Step 23: 5016 + 228 = 5244
Step 24: 5244 + 228 = 5472
Step 25: 5472 + 228 = 5700
Step 26: 5700 + 228 = 5928
Step 27: 5928 + 228 = 6156
Step 28: 6156 + 228 = 6384
Step 29: 6384 + 228 = 6612
Step 30: 6612 + 228 = 6840
Step 31: 6840 + 228 = 7068

So, 228*31 = 7068
