Alright, let's solve this math problem step by step. First, we have the number 375. 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 375 and add it to itself 19 times.
Step 1: 0 + 375 = 375
Step 2: 375 + 375 = 750
Step 3: 750 + 375 = 1125
Step 4: 1125 + 375 = 1500
Step 5: 1500 + 375 = 1875
Step 6: 1875 + 375 = 2250
Step 7: 2250 + 375 = 2625
Step 8: 2625 + 375 = 3000
Step 9: 3000 + 375 = 3375
Step 10: 3375 + 375 = 3750
Step 11: 3750 + 375 = 4125
Step 12: 4125 + 375 = 4500
Step 13: 4500 + 375 = 4875
Step 14: 4875 + 375 = 5250
Step 15: 5250 + 375 = 5625
Step 16: 5625 + 375 = 6000
Step 17: 6000 + 375 = 6375
Step 18: 6375 + 375 = 6750
Step 19: 6750 + 375 = 7125

So, 375*19 = 7125
