Alright, let's solve this math problem step by step. First, we have the number 308. 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 308 and add it to itself 30 times.
Step 1: 0 + 308 = 308
Step 2: 308 + 308 = 616
Step 3: 616 + 308 = 924
Step 4: 924 + 308 = 1232
Step 5: 1232 + 308 = 1540
Step 6: 1540 + 308 = 1848
Step 7: 1848 + 308 = 2156
Step 8: 2156 + 308 = 2464
Step 9: 2464 + 308 = 2772
Step 10: 2772 + 308 = 3080
Step 11: 3080 + 308 = 3388
Step 12: 3388 + 308 = 3696
Step 13: 3696 + 308 = 4004
Step 14: 4004 + 308 = 4312
Step 15: 4312 + 308 = 4620
Step 16: 4620 + 308 = 4928
Step 17: 4928 + 308 = 5236
Step 18: 5236 + 308 = 5544
Step 19: 5544 + 308 = 5852
Step 20: 5852 + 308 = 6160
Step 21: 6160 + 308 = 6468
Step 22: 6468 + 308 = 6776
Step 23: 6776 + 308 = 7084
Step 24: 7084 + 308 = 7392
Step 25: 7392 + 308 = 7700
Step 26: 7700 + 308 = 8008
Step 27: 8008 + 308 = 8316
Step 28: 8316 + 308 = 8624
Step 29: 8624 + 308 = 8932
Step 30: 8932 + 308 = 9240

So, 308*30 = 9240
