Sure thing, let's get straight to it. We start with 29 and we're going to multiply it by 12, which means adding 29 to itself 12 times.
Step 1: 0 + 29 = 29
Step 2: 29 + 29 = 58
Step 3: 58 + 29 = 87
Step 4: 87 + 29 = 116
Step 5: 116 + 29 = 145
Step 6: 145 + 29 = 174
Step 7: 174 + 29 = 203
Step 8: 203 + 29 = 232
Step 9: 232 + 29 = 261
Step 10: 261 + 29 = 290
Step 11: 290 + 29 = 319
Step 12: 319 + 29 = 348

So, 29*12 = 348
