Alright, let's solve this math problem step by step. First, we have the number 975. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 4. So, we're going to take the number 975 and add it to itself 4 times.
Step 1: 0 + 975 = 975
Step 2: 975 + 975 = 1950
Step 3: 1950 + 975 = 2925
Step 4: 2925 + 975 = 3900

So, 975*4 = 3900
