Alright, let's solve this math problem step by step. First, we have the number 755. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 19. So, we're going to take the number 755 and add it to itself 19 times.
Step 1: 0 + 755 = 755
Step 2: 755 + 755 = 1510
Step 3: 1510 + 755 = 2265
Step 4: 2265 + 755 = 3020
Step 5: 3020 + 755 = 3775
Step 6: 3775 + 755 = 4530
Step 7: 4530 + 755 = 5285
Step 8: 5285 + 755 = 6040
Step 9: 6040 + 755 = 6795
Step 10: 6795 + 755 = 7550
Step 11: 7550 + 755 = 8305
Step 12: 8305 + 755 = 9060
Step 13: 9060 + 755 = 9815
Step 14: 9815 + 755 = 10570
Step 15: 10570 + 755 = 11325
Step 16: 11325 + 755 = 12080
Step 17: 12080 + 755 = 12835
Step 18: 12835 + 755 = 13590
Step 19: 13590 + 755 = 14345

So, 755*19 = 14345
