Alright, let's solve this math problem step by step. First, we have the number 228. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 20. So, we're going to take the number 228 and add it to itself 20 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

So, 228*20 = 4560
