Let's get this math done. We have 6 and we're going to multiply it by 51. This is the same as taking 6 and adding it to itself 51 times.
Step 1: 0 + 6 = 6
Step 2: 6 + 6 = 12
Step 3: 12 + 6 = 18
Step 4: 18 + 6 = 24
Step 5: 24 + 6 = 30
Step 6: 30 + 6 = 36
Step 7: 36 + 6 = 42
Step 8: 42 + 6 = 48
Step 9: 48 + 6 = 54
Step 10: 54 + 6 = 60
Step 11: 60 + 6 = 66
Step 12: 66 + 6 = 72
Step 13: 72 + 6 = 78
Step 14: 78 + 6 = 84
Step 15: 84 + 6 = 90
Step 16: 90 + 6 = 96
Step 17: 96 + 6 = 102
Step 18: 102 + 6 = 108
Step 19: 108 + 6 = 114
Step 20: 114 + 6 = 120
Step 21: 120 + 6 = 126
Step 22: 126 + 6 = 132
Step 23: 132 + 6 = 138
Step 24: 138 + 6 = 144
Step 25: 144 + 6 = 150
Step 26: 150 + 6 = 156
Step 27: 156 + 6 = 162
Step 28: 162 + 6 = 168
Step 29: 168 + 6 = 174
Step 30: 174 + 6 = 180
Step 31: 180 + 6 = 186
Step 32: 186 + 6 = 192
Step 33: 192 + 6 = 198
Step 34: 198 + 6 = 204
Step 35: 204 + 6 = 210
Step 36: 210 + 6 = 216
Step 37: 216 + 6 = 222
Step 38: 222 + 6 = 228
Step 39: 228 + 6 = 234
Step 40: 234 + 6 = 240
Step 41: 240 + 6 = 246
Step 42: 246 + 6 = 252
Step 43: 252 + 6 = 258
Step 44: 258 + 6 = 264
Step 45: 264 + 6 = 270
Step 46: 270 + 6 = 276
Step 47: 276 + 6 = 282
Step 48: 282 + 6 = 288
Step 49: 288 + 6 = 294
Step 50: 294 + 6 = 300
Step 51: 300 + 6 = 306

So, 6*51 = 306
