Alright, let's solve this math problem step by step. First, we have the number 758. 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 758 and add it to itself 19 times.
Step 1: 0 + 758 = 758
Step 2: 758 + 758 = 1516
Step 3: 1516 + 758 = 2274
Step 4: 2274 + 758 = 3032
Step 5: 3032 + 758 = 3790
Step 6: 3790 + 758 = 4548
Step 7: 4548 + 758 = 5306
Step 8: 5306 + 758 = 6064
Step 9: 6064 + 758 = 6822
Step 10: 6822 + 758 = 7580
Step 11: 7580 + 758 = 8338
Step 12: 8338 + 758 = 9096
Step 13: 9096 + 758 = 9854
Step 14: 9854 + 758 = 10612
Step 15: 10612 + 758 = 11370
Step 16: 11370 + 758 = 12128
Step 17: 12128 + 758 = 12886
Step 18: 12886 + 758 = 13644
Step 19: 13644 + 758 = 14402

So, 758*19 = 14402
