Alright, let's solve this math problem step by step. First, we have the number 190. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 15. So, we're going to take the number 190 and add it to itself 15 times.
Step 1: 0 + 190 = 190
Step 2: 190 + 190 = 380
Step 3: 380 + 190 = 570
Step 4: 570 + 190 = 760
Step 5: 760 + 190 = 950
Step 6: 950 + 190 = 1140
Step 7: 1140 + 190 = 1330
Step 8: 1330 + 190 = 1520
Step 9: 1520 + 190 = 1710
Step 10: 1710 + 190 = 1900
Step 11: 1900 + 190 = 2090
Step 12: 2090 + 190 = 2280
Step 13: 2280 + 190 = 2470
Step 14: 2470 + 190 = 2660
Step 15: 2660 + 190 = 2850

So, 190*15 = 2850
