Step 28: 594 + 22 = 616
Step 29: 616 + 22 = 638
Step 30: 638 + 22 = 660
Step 31: 660 + 22 = 682
Step 32: 682 + 22 = 704
Step 33: 704 + 22 = 726
Step 34: 726 + 22 = 748
Step 35: 748 + 22 = 770
Step 36: 770 + 22 = 792
Step 37: 792 + 22 = 814
Step 38: 814 + 22 = 836
Step 39: 836 + 22 = 858
Step 40: 858 + 22 = 880
Step 41: 880 + 22 = 902
Step 42: 902 + 22 = 924
Step 43: 924 + 22 = 946
Step 44: 946 + 22 = 968
Step 45: 968 + 22 = 990
Step 46: 990 + 22 = 1012
Step 47: 1012 + 22 = 1034
Step 48: 1034 + 22 = 1056
Step 49: 1056 + 22 = 1078
Step 50: 1078 + 22 = 1100
Step 51: 1100 + 22 = 1122
Step 52: 1122 + 22 = 1144
Step 53: 1144 + 22 = 1166
Step 54: 1166 + 22 = 1188
Step 55: 1188 + 22 = 1210
Step 56: 1210 + 22 = 1232
Step 57: 1232 + 22 = 1254
Step 58: 1254 + 22 = 1276
Step 59: 1276 + 22 = 1298
Step 60: 1298 + 22 = 1320
Step 61: 1320 + 22 = 1342
Step 62: 1342 + 22 = 1364
Step 63: 1364 + 22 = 1386
Step 64: 1386 + 22 = 1408
Step 65: 1408 + 22 = 1430
Step 66: 1430 + 22 = 1452
Step 67: 1452 + 22 = 1474
Step 68: 1474 + 22 = 1496
Step 69: 1496 + 22 = 1518
Step 70: 1518 + 22 = 1540

So, 22*70 = 1540
