Alright, let's solve this math problem step by step. First, we have the number 266. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 16. So, we're going to take the number 266 and add it to itself 16 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
Step 10: 2394 + 266 = 2660
Step 11: 2660 + 266 = 2926
Step 12: 2926 + 266 = 3192
Step 13: 3192 + 266 = 3458
Step 14: 3458 + 266 = 3724
Step 15: 3724 + 266 = 3990
Step 16: 3990 + 266 = 4256

So, 266*16 = 4256
