Alright, let's solve this math problem step by step. First, we have the number 778. 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 778 and add it to itself 9 times.
Step 1: 0 + 778 = 778
Step 2: 778 + 778 = 1556
Step 3: 1556 + 778 = 2334
Step 4: 2334 + 778 = 3112
Step 5: 3112 + 778 = 3890
Step 6: 3890 + 778 = 4668
Step 7: 4668 + 778 = 5446
Step 8: 5446 + 778 = 6224
Step 9: 6224 + 778 = 7002

So, 778*9 = 7002
