Alright, let's solve this math problem step by step. First, we have the number 250. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 17. So, we're going to take the number 250 and add it to itself 17 times.
Step 1: 0 + 250 = 250
Step 2: 250 + 250 = 500
Step 3: 500 + 250 = 750
Step 4: 750 + 250 = 1000
Step 5: 1000 + 250 = 1250
Step 6: 1250 + 250 = 1500
Step 7: 1500 + 250 = 1750
Step 8: 1750 + 250 = 2000
Step 9: 2000 + 250 = 2250
Step 10: 2250 + 250 = 2500
Step 11: 2500 + 250 = 2750
Step 12: 2750 + 250 = 3000
Step 13: 3000 + 250 = 3250
Step 14: 3250 + 250 = 3500
Step 15: 3500 + 250 = 3750
Step 16: 3750 + 250 = 4000
Step 17: 4000 + 250 = 4250

So, 250*17 = 4250
