OK, let's work through this together. We're starting with 382 and we're going to multiply it by 20, which means we add 382 to itself 20 times.
Step 1: 0 + 382 = 382
Step 2: 382 + 382 = 764
Step 3: 764 + 382 = 1146
Step 4: 1146 + 382 = 1528
Step 5: 1528 + 382 = 1910
Step 6: 1910 + 382 = 2292
Step 7: 2292 + 382 = 2674
Step 8: 2674 + 382 = 3056
Step 9: 3056 + 382 = 3438
Step 10: 3438 + 382 = 3820
Step 11: 3820 + 382 = 4202
Step 12: 4202 + 382 = 4584
Step 13: 4584 + 382 = 4966
Step 14: 4966 + 382 = 5348
Step 15: 5348 + 382 = 5730
Step 16: 5730 + 382 = 6112
Step 17: 6112 + 382 = 6494
Step 18: 6494 + 382 = 6876
Step 19: 6876 + 382 = 7258
Step 20: 7258 + 382 = 7640

So, 382*20 = 7640
