Alright, let's solve this math problem step by step. First, we have the number 392. 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 392 and add it to itself 7 times.
Step 1: 0 + 392 = 392
Step 2: 392 + 392 = 784
Step 3: 784 + 392 = 1176
Step 4: 1176 + 392 = 1568
Step 5: 1568 + 392 = 1960
Step 6: 1960 + 392 = 2352
Step 7: 2352 + 392 = 2744

So, 392*7 = 2744
