Alright, let's solve this math problem step by step. First, we have the number 649. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 10. So, we're going to take the number 649 and add it to itself 10 times.
Step 1: 0 + 649 = 649
Step 2: 649 + 649 = 1298
Step 3: 1298 + 649 = 1947
Step 4: 1947 + 649 = 2596
Step 5: 2596 + 649 = 3245
Step 6: 3245 + 649 = 3894
Step 7: 3894 + 649 = 4543
Step 8: 4543 + 649 = 5192
Step 9: 5192 + 649 = 5841
Step 10: 5841 + 649 = 6490

So, 649*10 = 6490
