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 7. So, we're going to take the number 250 and add it to itself 7 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

So, 250*7 = 1750
