Alright, let's solve this math problem step by step. First, we have the number 459. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 18. So, we're going to take the number 459 and add it to itself 18 times.
Step 1: 0 + 459 = 459
Step 2: 459 + 459 = 918
Step 3: 918 + 459 = 1377
Step 4: 1377 + 459 = 1836
Step 5: 1836 + 459 = 2295
Step 6: 2295 + 459 = 2754
Step 7: 2754 + 459 = 3213
Step 8: 3213 + 459 = 3672
Step 9: 3672 + 459 = 4131
Step 10: 4131 + 459 = 4590
Step 11: 4590 + 459 = 5049
Step 12: 5049 + 459 = 5508
Step 13: 5508 + 459 = 5967
Step 14: 5967 + 459 = 6426
Step 15: 6426 + 459 = 6885
Step 16: 6885 + 459 = 7344
Step 17: 7344 + 459 = 7803
Step 18: 7803 + 459 = 8262

So, 459*18 = 8262
