Alright, let's solve this math problem step by step. First, we have the number 144. 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 144 and add it to itself 18 times.
Step 1: 0 + 144 = 144
Step 2: 144 + 144 = 288
Step 3: 288 + 144 = 432
Step 4: 432 + 144 = 576
Step 5: 576 + 144 = 720
Step 6: 720 + 144 = 864
Step 7: 864 + 144 = 1008
Step 8: 1008 + 144 = 1152
Step 9: 1152 + 144 = 1296
Step 10: 1296 + 144 = 1440
Step 11: 1440 + 144 = 1584
Step 12: 1584 + 144 = 1728
Step 13: 1728 + 144 = 1872
Step 14: 1872 + 144 = 2016
Step 15: 2016 + 144 = 2160
Step 16: 2160 + 144 = 2304
Step 17: 2304 + 144 = 2448
Step 18: 2448 + 144 = 2592

So, 144*18 = 2592
