Alright, let's solve this math problem step by step. First, we have the number 380. 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 380 and add it to itself 20 times.
Step 1: 0 + 380 = 380
Step 2: 380 + 380 = 760
Step 3: 760 + 380 = 1140
Step 4: 1140 + 380 = 1520
Step 5: 1520 + 380 = 1900
Step 6: 1900 + 380 = 2280
Step 7: 2280 + 380 = 2660
Step 8: 2660 + 380 = 3040
Step 9: 3040 + 380 = 3420
Step 10: 3420 + 380 = 3800
Step 11: 3800 + 380 = 4180
Step 12: 4180 + 380 = 4560
Step 13: 4560 + 380 = 4940
Step 14: 4940 + 380 = 5320
Step 15: 5320 + 380 = 5700
Step 16: 5700 + 380 = 6080
Step 17: 6080 + 380 = 6460
Step 18: 6460 + 380 = 6840
Step 19: 6840 + 380 = 7220
Step 20: 7220 + 380 = 7600

So, 380*20 = 7600
