Alright, let's solve this math problem step by step. First, we have the number 152. 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 152 and add it to itself 30 times.
Step 1: 0 + 152 = 152
Step 2: 152 + 152 = 304
Step 3: 304 + 152 = 456
Step 4: 456 + 152 = 608
Step 5: 608 + 152 = 760
Step 6: 760 + 152 = 912
Step 7: 912 + 152 = 1064
Step 8: 1064 + 152 = 1216
Step 9: 1216 + 152 = 1368
Step 10: 1368 + 152 = 1520
Step 11: 1520 + 152 = 1672
Step 12: 1672 + 152 = 1824
Step 13: 1824 + 152 = 1976
Step 14: 1976 + 152 = 2128
Step 15: 2128 + 152 = 2280
Step 16: 2280 + 152 = 2432
Step 17: 2432 + 152 = 2584
Step 18: 2584 + 152 = 2736
Step 19: 2736 + 152 = 2888
Step 20: 2888 + 152 = 3040
Step 21: 3040 + 152 = 3192
Step 22: 3192 + 152 = 3344
Step 23: 3344 + 152 = 3496
Step 24: 3496 + 152 = 3648
Step 25: 3648 + 152 = 3800
Step 26: 3800 + 152 = 3952
Step 27: 3952 + 152 = 4104
Step 28: 4104 + 152 = 4256
Step 29: 4256 + 152 = 4408
Step 30: 4408 + 152 = 4560

So, 152*30 = 4560
