Let's roll up our sleeves and solve this. We have 266 and we're going to multiply it by 9, essentially adding 266 to itself 9 times.
Step 1: 0 + 266 = 266
Step 2: 266 + 266 = 532
Step 3: 532 + 266 = 798
Step 4: 798 + 266 = 1064
Step 5: 1064 + 266 = 1330
Step 6: 1330 + 266 = 1596
Step 7: 1596 + 266 = 1862
Step 8: 1862 + 266 = 2128
Step 9: 2128 + 266 = 2394

So, 266*9 = 2394
