Sure thing, let's get straight to it. We start with 140 and we're going to multiply it by 56, which means adding 140 to itself 56 times.
Step 1: 0 + 140 = 140
Step 2: 140 + 140 = 280
Step 3: 280 + 140 = 420
Step 4: 420 + 140 = 560
Step 5: 560 + 140 = 700
Step 6: 700 + 140 = 840
Step 7: 840 + 140 = 980
Step 8: 980 + 140 = 1120
Step 9: 1120 + 140 = 1260
Step 10: 1260 + 140 = 1400
Step 11: 1400 + 140 = 1540
Step 12: 1540 + 140 = 1680
Step 13: 1680 + 140 = 1820
Step 14: 1820 + 140 = 1960
Step 15: 1960 + 140 = 2100
Step 16: 2100 + 140 = 2240
Step 17: 2240 + 140 = 2380
Step 18: 2380 + 140 = 2520
Step 19: 2520 + 140 = 2660
Step 20: 2660 + 140 = 2800
Step 21: 2800 + 140 = 2940
Step 22: 2940 + 140 = 3080
Step 23: 3080 + 140 = 3220
Step 24: 3220 + 140 = 3360
Step 25: 3360 + 140 = 3500
Step 26: 3500 + 140 = 3640
Step 27: 3640 + 140 = 3780
Step 28: 3780 + 140 = 3920
Step 29: 3920 + 140 = 4060
Step 30: 4060 + 140 = 4200
Step 31: 4200 + 140 = 4340
Step 32: 4340 + 140 = 4480
Step 33: 4480 + 140 = 4620
Step 34: 4620 + 140 = 4760
Step 35: 4760 + 140 = 4900
Step 36: 4900 + 140 = 5040
Step 37: 5040 + 140 = 5180
Step 38: 5180 + 140 = 5320
Step 39: 5320 + 140 = 5460
Step 40: 5460 + 140 = 5600
Step 41: 5600 + 140 = 5740
Step 42: 5740 + 140 = 5880
Step 43: 5880 + 140 = 6020
Step 44: 6020 + 140 = 6160
Step 45: 6160 + 140 = 6300
Step 46: 6300 + 140 = 6440
Step 47: 6440 + 140 = 6580
Step 48: 6580 + 140 = 6720
Step 49: 6720 + 140 = 6860
Step 50: 6860 + 140 = 7000
Step 51: 7000 + 140 = 7140
Step 52: 7140 + 140 = 7280
Step 53: 7280 + 140 = 7420
Step 54: 7420 + 140 = 7560
Step 55: 7560 + 140 = 7700
Step 56: 7700 + 140 = 7840

So, 140*56 = 7840
