Alright, let's solve this math problem step by step. First, we have the number 256. 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 256 and add it to itself 7 times.
Step 1: 0 + 256 = 256
Step 2: 256 + 256 = 512
Step 3: 512 + 256 = 768
Step 4: 768 + 256 = 1024
Step 5: 1024 + 256 = 1280
Step 6: 1280 + 256 = 1536
Step 7: 1536 + 256 = 1792

So, 256*7 = 1792
