Alright, let's solve this math problem step by step. First, we have the number 312. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 6. So, we're going to take the number 312 and add it to itself 6 times.
Step 1: 0 + 312 = 312
Step 2: 312 + 312 = 624
Step 3: 624 + 312 = 936
Step 4: 936 + 312 = 1248
Step 5: 1248 + 312 = 1560
Step 6: 1560 + 312 = 1872

So, 312*6 = 1872
