Sure thing! We've got 380 and we're gonna multiply it by 7. That's the same as adding 380 to itself 7 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

So, 380*7 = 2660
