Alright, let's solve this math problem step by step. First, we have the number 78. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 33. So, we're going to take the number 78 and add it to itself 33 times.
Step 1: 0 + 78 = 78
Step 2: 78 + 78 = 156
Step 3: 156 + 78 = 234
Step 4: 234 + 78 = 312
Step 5: 312 + 78 = 390
Step 6: 390 + 78 = 468
Step 7: 468 + 78 = 546
Step 8: 546 + 78 = 624
Step 9: 624 + 78 = 702
Step 10: 702 + 78 = 780
Step 11: 780 + 78 = 858
Step 12: 858 + 78 = 936
Step 13: 936 + 78 = 1014
Step 14: 1014 + 78 = 1092
Step 15: 1092 + 78 = 1170
Step 16: 1170 + 78 = 1248
Step 17: 1248 + 78 = 1326
Step 18: 1326 + 78 = 1404
Step 19: 1404 + 78 = 1482
Step 20: 1482 + 78 = 1560
Step 21: 1560 + 78 = 1638
Step 22: 1638 + 78 = 1716
Step 23: 1716 + 78 = 1794
Step 24: 1794 + 78 = 1872
Step 25: 1872 + 78 = 1950
Step 26: 1950 + 78 = 2028
Step 27: 2028 + 78 = 2106
Step 28: 2106 + 78 = 2184
Step 29: 2184 + 78 = 2262
Step 30: 2262 + 78 = 2340
Step 31: 2340 + 78 = 2418
Step 32: 2418 + 78 = 2496
Step 33: 2496 + 78 = 2574

So, 78*33 = 2574
