Step 8: 210 + 30 = 240
Step 9: 240 + 30 = 270
Step 10: 270 + 30 = 300
Step 11: 300 + 30 = 330
Step 12: 330 + 30 = 360
Step 13: 360 + 30 = 390
Step 14: 390 + 30 = 420
Step 15: 420 + 30 = 450
Step 16: 450 + 30 = 480
Step 17: 480 + 30 = 510
Step 18: 510 + 30 = 540
Step 19: 540 + 30 = 570
Step 20: 570 + 30 = 600
Step 21: 600 + 30 = 630
Step 22: 630 + 30 = 660
Step 23: 660 + 30 = 690
Step 24: 690 + 30 = 720
Step 25: 720 + 30 = 750
Step 26: 750 + 30 = 780
Step 27: 780 + 30 = 810
Step 28: 810 + 30 = 840
Step 29: 840 + 30 = 870
Step 30: 870 + 30 = 900
Step 31: 900 + 30 = 930
Step 32: 930 + 30 = 960
Step 33: 960 + 30 = 990
Step 34: 990 + 30 = 1020
Step 35: 1020 + 30 = 1050
Step 36: 1050 + 30 = 1080
Step 37: 1080 + 30 = 1110
Step 38: 1110 + 30 = 1140
Step 39: 1140 + 30 = 1170
Step 40: 1170 + 30 = 1200
Step 41: 1200 + 30 = 1230
Step 42: 1230 + 30 = 1260
Step 43: 1260 + 30 = 1290
Step 44: 1290 + 30 = 1320
Step 45: 1320 + 30 = 1350
Step 46: 1350 + 30 = 1380
Step 47: 1380 + 30 = 1410
Step 48: 1410 + 30 = 1440
Step 49: 1440 + 30 = 1470
Step 50: 1470 + 30 = 1500
Step 51: 1500 + 30 = 1530
Step 52: 1530 + 30 = 1560
Step 53: 1560 + 30 = 1590
Step 54: 1590 + 30 = 1620
Step 55: 1620 + 30 = 1650
Step 56: 1650 + 30 = 1680
Step 57: 1680 + 30 = 1710
Step 58: 1710 + 30 = 1740
Step 59: 1740 + 30 = 1770
Step 60: 1770 + 30 = 1800
Step 61: 1800 + 30 = 1830
Step 62: 1830 + 30 = 1860
Step 63: 1860 + 30 = 1890
Step 64: 1890 + 30 = 1920
Step 65: 1920 + 30 = 1950
Step 66: 1950 + 30 = 1980
Step 67: 1980 + 30 = 2010
Step 68: 2010 + 30 = 2040
Step 69: 2040 + 30 = 2070
Step 70: 2070 + 30 = 2100
Step 71: 2100 + 30 = 2130
Step 72: 2130 + 30 = 2160
Step 73: 2160 + 30 = 2190
Step 74: 2190 + 30 = 2220
Step 75: 2220 + 30 = 2250
Step 76: 2250 + 30 = 2280
Step 77: 2280 + 30 = 2310
Step 78: 2310 + 30 = 2340
Step 79: 2340 + 30 = 2370
Step 80: 2370 + 30 = 2400

So, 30*80 = 2400
