Alright, let's solve this math problem step by step. First, we have the number 752. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 20. So, we're going to take the number 752 and add it to itself 20 times.
Step 1: 0 + 752 = 752
Step 2: 752 + 752 = 1504
Step 3: 1504 + 752 = 2256
Step 4: 2256 + 752 = 3008
Step 5: 3008 + 752 = 3760
Step 6: 3760 + 752 = 4512
Step 7: 4512 + 752 = 5264
Step 8: 5264 + 752 = 6016
Step 9: 6016 + 752 = 6768
Step 10: 6768 + 752 = 7520
Step 11: 7520 + 752 = 8272
Step 12: 8272 + 752 = 9024
Step 13: 9024 + 752 = 9776
Step 14: 9776 + 752 = 10528
Step 15: 10528 + 752 = 11280
Step 16: 11280 + 752 = 12032
Step 17: 12032 + 752 = 12784
Step 18: 12784 + 752 = 13536
Step 19: 13536 + 752 = 14288
Step 20: 14288 + 752 = 15040

So, 752*20 = 15040
