OK, let's crack this. We're given 380 and our task is to multiply it by 25. Essentially, we'll be adding 380 to itself 25 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
Step 21: 7600 + 380 = 7980
Step 22: 7980 + 380 = 8360
Step 23: 8360 + 380 = 8740
Step 24: 8740 + 380 = 9120
Step 25: 9120 + 380 = 9500

So, 380*25 = 9500
