Alright, let's solve this math problem step by step. First, we have the number 846. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 846 and add it to itself 9 times.
Step 1: 0 + 846 = 846
Step 2: 846 + 846 = 1692
Step 3: 1692 + 846 = 2538
Step 4: 2538 + 846 = 3384
Step 5: 3384 + 846 = 4230
Step 6: 4230 + 846 = 5076
Step 7: 5076 + 846 = 5922
Step 8: 5922 + 846 = 6768
Step 9: 6768 + 846 = 7614

So, 846*9 = 7614
