Step 7: 1860 + 310 = 2170
Step 8: 2170 + 310 = 2480
Step 9: 2480 + 310 = 2790
Step 10: 2790 + 310 = 3100
Step 11: 3100 + 310 = 3410
Step 12: 3410 + 310 = 3720
Step 13: 3720 + 310 = 4030
Step 14: 4030 + 310 = 4340
Step 15: 4340 + 310 = 4650
Step 16: 4650 + 310 = 4960
Step 17: 4960 + 310 = 5270
Step 18: 5270 + 310 = 5580
Step 19: 5580 + 310 = 5890
Step 20: 5890 + 310 = 6200
Step 21: 6200 + 310 = 6510
Step 22: 6510 + 310 = 6820
Step 23: 6820 + 310 = 7130
Step 24: 7130 + 310 = 7440
Step 25: 7440 + 310 = 7750
Step 26: 7750 + 310 = 8060
Step 27: 8060 + 310 = 8370
Step 28: 8370 + 310 = 8680
Step 29: 8680 + 310 = 8990
Step 30: 8990 + 310 = 9300
Step 31: 9300 + 310 = 9610
Step 32: 9610 + 310 = 9920
Step 33: 9920 + 310 = 10230
Step 34: 10230 + 310 = 10540
Step 35: 10540 + 310 = 10850
Step 36: 10850 + 310 = 11160
Step 37: 11160 + 310 = 11470
Step 38: 11470 + 310 = 11780
Step 39: 11780 + 310 = 12090
Step 40: 12090 + 310 = 12400
Step 41: 12400 + 310 = 12710
Step 42: 12710 + 310 = 13020
Step 43: 13020 + 310 = 13330
Step 44: 13330 + 310 = 13640
Step 45: 13640 + 310 = 13950
Step 46: 13950 + 310 = 14260
Step 47: 14260 + 310 = 14570
Step 48: 14570 + 310 = 14880
Step 49: 14880 + 310 = 15190
Step 50: 15190 + 310 = 15500
Step 51: 15500 + 310 = 15810
Step 52: 15810 + 310 = 16120
Step 53: 16120 + 310 = 16430
Step 54: 16430 + 310 = 16740
Step 55: 16740 + 310 = 17050
Step 56: 17050 + 310 = 17360
Step 57: 17360 + 310 = 17670
Step 58: 17670 + 310 = 17980

So, 310*58 = 17980
