Alright, let's solve this math problem step by step. First, we have the number 189. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 30. So, we're going to take the number 189 and add it to itself 30 times.
Step 1: 0 + 189 = 189
Step 2: 189 + 189 = 378
Step 3: 378 + 189 = 567
Step 4: 567 + 189 = 756
Step 5: 756 + 189 = 945
Step 6: 945 + 189 = 1134
Step 7: 1134 + 189 = 1323
Step 8: 1323 + 189 = 1512
Step 9: 1512 + 189 = 1701
Step 10: 1701 + 189 = 1890
Step 11: 1890 + 189 = 2079
Step 12: 2079 + 189 = 2268
Step 13: 2268 + 189 = 2457
Step 14: 2457 + 189 = 2646
Step 15: 2646 + 189 = 2835
Step 16: 2835 + 189 = 3024
Step 17: 3024 + 189 = 3213
Step 18: 3213 + 189 = 3402
Step 19: 3402 + 189 = 3591
Step 20: 3591 + 189 = 3780
Step 21: 3780 + 189 = 3969
Step 22: 3969 + 189 = 4158
Step 23: 4158 + 189 = 4347
Step 24: 4347 + 189 = 4536
Step 25: 4536 + 189 = 4725
Step 26: 4725 + 189 = 4914
Step 27: 4914 + 189 = 5103
Step 28: 5103 + 189 = 5292
Step 29: 5292 + 189 = 5481
Step 30: 5481 + 189 = 5670

So, 189*30 = 5670
