Alright, let's solve this math problem step by step. First, we have the number 883. 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 883 and add it to itself 20 times.
Step 1: 0 + 883 = 883
Step 2: 883 + 883 = 1766
Step 3: 1766 + 883 = 2649
Step 4: 2649 + 883 = 3532
Step 5: 3532 + 883 = 4415
Step 6: 4415 + 883 = 5298
Step 7: 5298 + 883 = 6181
Step 8: 6181 + 883 = 7064
Step 9: 7064 + 883 = 7947
Step 10: 7947 + 883 = 8830
Step 11: 8830 + 883 = 9713
Step 12: 9713 + 883 = 10596
Step 13: 10596 + 883 = 11479
Step 14: 11479 + 883 = 12362
Step 15: 12362 + 883 = 13245
Step 16: 13245 + 883 = 14128
Step 17: 14128 + 883 = 15011
Step 18: 15011 + 883 = 15894
Step 19: 15894 + 883 = 16777
Step 20: 16777 + 883 = 17660

So, 883*20 = 17660
