Alright, let's solve this math problem step by step. First, we have the number 146. 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 146 and add it to itself 30 times.
Step 1: 0 + 146 = 146
Step 2: 146 + 146 = 292
Step 3: 292 + 146 = 438
Step 4: 438 + 146 = 584
Step 5: 584 + 146 = 730
Step 6: 730 + 146 = 876
Step 7: 876 + 146 = 1022
Step 8: 1022 + 146 = 1168
Step 9: 1168 + 146 = 1314
Step 10: 1314 + 146 = 1460
Step 11: 1460 + 146 = 1606
Step 12: 1606 + 146 = 1752
Step 13: 1752 + 146 = 1898
Step 14: 1898 + 146 = 2044
Step 15: 2044 + 146 = 2190
Step 16: 2190 + 146 = 2336
Step 17: 2336 + 146 = 2482
Step 18: 2482 + 146 = 2628
Step 19: 2628 + 146 = 2774
Step 20: 2774 + 146 = 2920
Step 21: 2920 + 146 = 3066
Step 22: 3066 + 146 = 3212
Step 23: 3212 + 146 = 3358
Step 24: 3358 + 146 = 3504
Step 25: 3504 + 146 = 3650
Step 26: 3650 + 146 = 3796
Step 27: 3796 + 146 = 3942
Step 28: 3942 + 146 = 4088
Step 29: 4088 + 146 = 4234
Step 30: 4234 + 146 = 4380

So, 146*30 = 4380
