Alright, let's solve this math problem step by step. First, we have the number 432. 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 432 and add it to itself 30 times.
Step 1: 0 + 432 = 432
Step 2: 432 + 432 = 864
Step 3: 864 + 432 = 1296
Step 4: 1296 + 432 = 1728
Step 5: 1728 + 432 = 2160
Step 6: 2160 + 432 = 2592
Step 7: 2592 + 432 = 3024
Step 8: 3024 + 432 = 3456
Step 9: 3456 + 432 = 3888
Step 10: 3888 + 432 = 4320
Step 11: 4320 + 432 = 4752
Step 12: 4752 + 432 = 5184
Step 13: 5184 + 432 = 5616
Step 14: 5616 + 432 = 6048
Step 15: 6048 + 432 = 6480
Step 16: 6480 + 432 = 6912
Step 17: 6912 + 432 = 7344
Step 18: 7344 + 432 = 7776
Step 19: 7776 + 432 = 8208
Step 20: 8208 + 432 = 8640
Step 21: 8640 + 432 = 9072
Step 22: 9072 + 432 = 9504
Step 23: 9504 + 432 = 9936
Step 24: 9936 + 432 = 10368
Step 25: 10368 + 432 = 10800
Step 26: 10800 + 432 = 11232
Step 27: 11232 + 432 = 11664
Step 28: 11664 + 432 = 12096
Step 29: 12096 + 432 = 12528
Step 30: 12528 + 432 = 12960

So, 432*30 = 12960
