Let's get this math done. We have 304 and we're going to multiply it by 39. This is the same as taking 304 and adding it to itself 39 times.
Step 1: 0 + 304 = 304
Step 2: 304 + 304 = 608
Step 3: 608 + 304 = 912
Step 4: 912 + 304 = 1216
Step 5: 1216 + 304 = 1520
Step 6: 1520 + 304 = 1824
Step 7: 1824 + 304 = 2128
Step 8: 2128 + 304 = 2432
Step 9: 2432 + 304 = 2736
Step 10: 2736 + 304 = 3040
Step 11: 3040 + 304 = 3344
Step 12: 3344 + 304 = 3648
Step 13: 3648 + 304 = 3952
Step 14: 3952 + 304 = 4256
Step 15: 4256 + 304 = 4560
Step 16: 4560 + 304 = 4864
Step 17: 4864 + 304 = 5168
Step 18: 5168 + 304 = 5472
Step 19: 5472 + 304 = 5776
Step 20: 5776 + 304 = 6080
Step 21: 6080 + 304 = 6384
Step 22: 6384 + 304 = 6688
Step 23: 6688 + 304 = 6992
Step 24: 6992 + 304 = 7296
Step 25: 7296 + 304 = 7600
Step 26: 7600 + 304 = 7904
Step 27: 7904 + 304 = 8208
Step 28: 8208 + 304 = 8512
Step 29: 8512 + 304 = 8816
Step 30: 8816 + 304 = 9120
Step 31: 9120 + 304 = 9424
Step 32: 9424 + 304 = 9728
Step 33: 9728 + 304 = 10032
Step 34: 10032 + 304 = 10336
Step 35: 10336 + 304 = 10640
Step 36: 10640 + 304 = 10944
Step 37: 10944 + 304 = 11248
Step 38: 11248 + 304 = 11552
Step 39: 11552 + 304 = 11856

So, 304*39 = 11856
