Alright, let's solve this math problem step by step. First, we have the number 625. 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 625 and add it to itself 33 times.
Step 1: 0 + 625 = 625
Step 2: 625 + 625 = 1250
Step 3: 1250 + 625 = 1875
Step 4: 1875 + 625 = 2500
Step 5: 2500 + 625 = 3125
Step 6: 3125 + 625 = 3750
Step 7: 3750 + 625 = 4375
Step 8: 4375 + 625 = 5000
Step 9: 5000 + 625 = 5625
Step 10: 5625 + 625 = 6250
Step 11: 6250 + 625 = 6875
Step 12: 6875 + 625 = 7500
Step 13: 7500 + 625 = 8125
Step 14: 8125 + 625 = 8750
Step 15: 8750 + 625 = 9375
Step 16: 9375 + 625 = 10000
Step 17: 10000 + 625 = 10625
Step 18: 10625 + 625 = 11250
Step 19: 11250 + 625 = 11875
Step 20: 11875 + 625 = 12500
Step 21: 12500 + 625 = 13125
Step 22: 13125 + 625 = 13750
Step 23: 13750 + 625 = 14375
Step 24: 14375 + 625 = 15000
Step 25: 15000 + 625 = 15625
Step 26: 15625 + 625 = 16250
Step 27: 16250 + 625 = 16875
Step 28: 16875 + 625 = 17500
Step 29: 17500 + 625 = 18125
Step 30: 18125 + 625 = 18750
Step 31: 18750 + 625 = 19375
Step 32: 19375 + 625 = 20000
Step 33: 20000 + 625 = 20625

So, 625*33 = 20625
