Alright, let's solve this math problem step by step. First, we have the number 275. 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 275 and add it to itself 18 times.
Step 1: 0 + 275 = 275
Step 2: 275 + 275 = 550
Step 3: 550 + 275 = 825
Step 4: 825 + 275 = 1100
Step 5: 1100 + 275 = 1375
Step 6: 1375 + 275 = 1650
Step 7: 1650 + 275 = 1925
Step 8: 1925 + 275 = 2200
Step 9: 2200 + 275 = 2475
Step 10: 2475 + 275 = 2750
Step 11: 2750 + 275 = 3025
Step 12: 3025 + 275 = 3300
Step 13: 3300 + 275 = 3575
Step 14: 3575 + 275 = 3850
Step 15: 3850 + 275 = 4125
Step 16: 4125 + 275 = 4400
Step 17: 4400 + 275 = 4675
Step 18: 4675 + 275 = 4950

So, 275*18 = 4950
