Alright, let's solve this math problem step by step. First, we have the number 938. 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 938 and add it to itself 30 times.
Step 1: 0 + 938 = 938
Step 2: 938 + 938 = 1876
Step 3: 1876 + 938 = 2814
Step 4: 2814 + 938 = 3752
Step 5: 3752 + 938 = 4690
Step 6: 4690 + 938 = 5628
Step 7: 5628 + 938 = 6566
Step 8: 6566 + 938 = 7504
Step 9: 7504 + 938 = 8442
Step 10: 8442 + 938 = 9380
Step 11: 9380 + 938 = 10318
Step 12: 10318 + 938 = 11256
Step 13: 11256 + 938 = 12194
Step 14: 12194 + 938 = 13132
Step 15: 13132 + 938 = 14070
Step 16: 14070 + 938 = 15008
Step 17: 15008 + 938 = 15946
Step 18: 15946 + 938 = 16884
Step 19: 16884 + 938 = 17822
Step 20: 17822 + 938 = 18760
Step 21: 18760 + 938 = 19698
Step 22: 19698 + 938 = 20636
Step 23: 20636 + 938 = 21574
Step 24: 21574 + 938 = 22512
Step 25: 22512 + 938 = 23450
Step 26: 23450 + 938 = 24388
Step 27: 24388 + 938 = 25326
Step 28: 25326 + 938 = 26264
Step 29: 26264 + 938 = 27202
Step 30: 27202 + 938 = 28140

So, 938*30 = 28140
