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 10. So, we're going to take the number 380 and add it to itself 10 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

So, 380*10 = 3800
