Alright, let's solve this math problem step by step. First, we have the number 216. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 11. So, we're going to take the number 216 and add it to itself 11 times.
Step 1: 0 + 216 = 216
Step 2: 216 + 216 = 432
Step 3: 432 + 216 = 648
Step 4: 648 + 216 = 864
Step 5: 864 + 216 = 1080
Step 6: 1080 + 216 = 1296
Step 7: 1296 + 216 = 1512
Step 8: 1512 + 216 = 1728
Step 9: 1728 + 216 = 1944
Step 10: 1944 + 216 = 2160
Step 11: 2160 + 216 = 2376

So, 216*11 = 2376
