Alright, let's solve this math problem step by step. First, we have the number 277. 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 277 and add it to itself 20 times.
Step 1: 0 + 277 = 277
Step 2: 277 + 277 = 554
Step 3: 554 + 277 = 831
Step 4: 831 + 277 = 1108
Step 5: 1108 + 277 = 1385
Step 6: 1385 + 277 = 1662
Step 7: 1662 + 277 = 1939
Step 8: 1939 + 277 = 2216
Step 9: 2216 + 277 = 2493
Step 10: 2493 + 277 = 2770
Step 11: 2770 + 277 = 3047
Step 12: 3047 + 277 = 3324
Step 13: 3324 + 277 = 3601
Step 14: 3601 + 277 = 3878
Step 15: 3878 + 277 = 4155
Step 16: 4155 + 277 = 4432
Step 17: 4432 + 277 = 4709
Step 18: 4709 + 277 = 4986
Step 19: 4986 + 277 = 5263
Step 20: 5263 + 277 = 5540

So, 277*20 = 5540
