Alright, let's solve this math problem step by step. First, we have the number 330. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 28. So, we're going to take the number 330 and add it to itself 28 times.
Step 1: 0 + 330 = 330
Step 2: 330 + 330 = 660
Step 3: 660 + 330 = 990
Step 4: 990 + 330 = 1320
Step 5: 1320 + 330 = 1650
Step 6: 1650 + 330 = 1980
Step 7: 1980 + 330 = 2310
Step 8: 2310 + 330 = 2640
Step 9: 2640 + 330 = 2970
Step 10: 2970 + 330 = 3300
Step 11: 3300 + 330 = 3630
Step 12: 3630 + 330 = 3960
Step 13: 3960 + 330 = 4290
Step 14: 4290 + 330 = 4620
Step 15: 4620 + 330 = 4950
Step 16: 4950 + 330 = 5280
Step 17: 5280 + 330 = 5610
Step 18: 5610 + 330 = 5940
Step 19: 5940 + 330 = 6270
Step 20: 6270 + 330 = 6600
Step 21: 6600 + 330 = 6930
Step 22: 6930 + 330 = 7260
Step 23: 7260 + 330 = 7590
Step 24: 7590 + 330 = 7920
Step 25: 7920 + 330 = 8250
Step 26: 8250 + 330 = 8580
Step 27: 8580 + 330 = 8910
Step 28: 8910 + 330 = 9240

So, 330*28 = 9240
