OK, let's crack this. We're given 26 and our task is to multiply it by 12. Essentially, we'll be adding 26 to itself 12 times.
Step 1: 0 + 26 = 26
Step 2: 26 + 26 = 52
Step 3: 52 + 26 = 78
Step 4: 78 + 26 = 104
Step 5: 104 + 26 = 130
Step 6: 130 + 26 = 156
Step 7: 156 + 26 = 182
Step 8: 182 + 26 = 208
Step 9: 208 + 26 = 234
Step 10: 234 + 26 = 260
Step 11: 260 + 26 = 286
Step 12: 286 + 26 = 312

So, 26*12 = 312
