Alright, let's solve this math problem step by step. First, we have the number 200. 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 200 and add it to itself 19 times.
Step 1: 0 + 200 = 200
Step 2: 200 + 200 = 400
Step 3: 400 + 200 = 600
Step 4: 600 + 200 = 800
Step 5: 800 + 200 = 1000
Step 6: 1000 + 200 = 1200
Step 7: 1200 + 200 = 1400
Step 8: 1400 + 200 = 1600
Step 9: 1600 + 200 = 1800
Step 10: 1800 + 200 = 2000
Step 11: 2000 + 200 = 2200
Step 12: 2200 + 200 = 2400
Step 13: 2400 + 200 = 2600
Step 14: 2600 + 200 = 2800
Step 15: 2800 + 200 = 3000
Step 16: 3000 + 200 = 3200
Step 17: 3200 + 200 = 3400
Step 18: 3400 + 200 = 3600
Step 19: 3600 + 200 = 3800

So, 200*19 = 3800
