OK, let's crack this. We're given 430 and our task is to multiply it by 27. Essentially, we'll be adding 430 to itself 27 times.
Step 1: 0 + 430 = 430
Step 2: 430 + 430 = 860
Step 3: 860 + 430 = 1290
Step 4: 1290 + 430 = 1720
Step 5: 1720 + 430 = 2150
Step 6: 2150 + 430 = 2580
Step 7: 2580 + 430 = 3010
Step 8: 3010 + 430 = 3440
Step 9: 3440 + 430 = 3870
Step 10: 3870 + 430 = 4300
Step 11: 4300 + 430 = 4730
Step 12: 4730 + 430 = 5160
Step 13: 5160 + 430 = 5590
Step 14: 5590 + 430 = 6020
Step 15: 6020 + 430 = 6450
Step 16: 6450 + 430 = 6880
Step 17: 6880 + 430 = 7310
Step 18: 7310 + 430 = 7740
Step 19: 7740 + 430 = 8170
Step 20: 8170 + 430 = 8600
Step 21: 8600 + 430 = 9030
Step 22: 9030 + 430 = 9460
Step 23: 9460 + 430 = 9890
Step 24: 9890 + 430 = 10320
Step 25: 10320 + 430 = 10750
Step 26: 10750 + 430 = 11180
Step 27: 11180 + 430 = 11610

So, 430*27 = 11610
