Alright, let's solve this math problem step by step. First, we have the number 282. 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 282 and add it to itself 20 times.
Step 1: 0 + 282 = 282
Step 2: 282 + 282 = 564
Step 3: 564 + 282 = 846
Step 4: 846 + 282 = 1128
Step 5: 1128 + 282 = 1410
Step 6: 1410 + 282 = 1692
Step 7: 1692 + 282 = 1974
Step 8: 1974 + 282 = 2256
Step 9: 2256 + 282 = 2538
Step 10: 2538 + 282 = 2820
Step 11: 2820 + 282 = 3102
Step 12: 3102 + 282 = 3384
Step 13: 3384 + 282 = 3666
Step 14: 3666 + 282 = 3948
Step 15: 3948 + 282 = 4230
Step 16: 4230 + 282 = 4512
Step 17: 4512 + 282 = 4794
Step 18: 4794 + 282 = 5076
Step 19: 5076 + 282 = 5358
Step 20: 5358 + 282 = 5640

So, 282*20 = 5640
