Alright, let's solve this math problem step by step. First, we have the number 998. 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 998 and add it to itself 7 times.
Step 1: 0 + 998 = 998
Step 2: 998 + 998 = 1996
Step 3: 1996 + 998 = 2994
Step 4: 2994 + 998 = 3992
Step 5: 3992 + 998 = 4990
Step 6: 4990 + 998 = 5988
Step 7: 5988 + 998 = 6986

So, 998*7 = 6986
