Alright, let's solve this math problem step by step. First, we have the number 520. 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 520 and add it to itself 33 times.
Step 1: 0 + 520 = 520
Step 2: 520 + 520 = 1040
Step 3: 1040 + 520 = 1560
Step 4: 1560 + 520 = 2080
Step 5: 2080 + 520 = 2600
Step 6: 2600 + 520 = 3120
Step 7: 3120 + 520 = 3640
Step 8: 3640 + 520 = 4160
Step 9: 4160 + 520 = 4680
Step 10: 4680 + 520 = 5200
Step 11: 5200 + 520 = 5720
Step 12: 5720 + 520 = 6240
Step 13: 6240 + 520 = 6760
Step 14: 6760 + 520 = 7280
Step 15: 7280 + 520 = 7800
Step 16: 7800 + 520 = 8320
Step 17: 8320 + 520 = 8840
Step 18: 8840 + 520 = 9360
Step 19: 9360 + 520 = 9880
Step 20: 9880 + 520 = 10400
Step 21: 10400 + 520 = 10920
Step 22: 10920 + 520 = 11440
Step 23: 11440 + 520 = 11960
Step 24: 11960 + 520 = 12480
Step 25: 12480 + 520 = 13000
Step 26: 13000 + 520 = 13520
Step 27: 13520 + 520 = 14040
Step 28: 14040 + 520 = 14560
Step 29: 14560 + 520 = 15080
Step 30: 15080 + 520 = 15600
Step 31: 15600 + 520 = 16120
Step 32: 16120 + 520 = 16640
Step 33: 16640 + 520 = 17160

So, 520*33 = 17160
