Step 8: 2072 + 296 = 2368
Step 9: 2368 + 296 = 2664
Step 10: 2664 + 296 = 2960
Step 11: 2960 + 296 = 3256
Step 12: 3256 + 296 = 3552
Step 13: 3552 + 296 = 3848
Step 14: 3848 + 296 = 4144
Step 15: 4144 + 296 = 4440
Step 16: 4440 + 296 = 4736
Step 17: 4736 + 296 = 5032
Step 18: 5032 + 296 = 5328
Step 19: 5328 + 296 = 5624
Step 20: 5624 + 296 = 5920
Step 21: 5920 + 296 = 6216
Step 22: 6216 + 296 = 6512
Step 23: 6512 + 296 = 6808
Step 24: 6808 + 296 = 7104
Step 25: 7104 + 296 = 7400
Step 26: 7400 + 296 = 7696
Step 27: 7696 + 296 = 7992
Step 28: 7992 + 296 = 8288
Step 29: 8288 + 296 = 8584
Step 30: 8584 + 296 = 8880
Step 31: 8880 + 296 = 9176
Step 32: 9176 + 296 = 9472
Step 33: 9472 + 296 = 9768
Step 34: 9768 + 296 = 10064
Step 35: 10064 + 296 = 10360
Step 36: 10360 + 296 = 10656
Step 37: 10656 + 296 = 10952
Step 38: 10952 + 296 = 11248
Step 39: 11248 + 296 = 11544
Step 40: 11544 + 296 = 11840
Step 41: 11840 + 296 = 12136
Step 42: 12136 + 296 = 12432
Step 43: 12432 + 296 = 12728
Step 44: 12728 + 296 = 13024
Step 45: 13024 + 296 = 13320
Step 46: 13320 + 296 = 13616
Step 47: 13616 + 296 = 13912
Step 48: 13912 + 296 = 14208
Step 49: 14208 + 296 = 14504
Step 50: 14504 + 296 = 14800
Step 51: 14800 + 296 = 15096

So, 296*51 = 15096
