Alright, let's solve this math problem step by step. First, we have the number 689. 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 689 and add it to itself 10 times.
Step 1: 0 + 689 = 689
Step 2: 689 + 689 = 1378
Step 3: 1378 + 689 = 2067
Step 4: 2067 + 689 = 2756
Step 5: 2756 + 689 = 3445
Step 6: 3445 + 689 = 4134
Step 7: 4134 + 689 = 4823
Step 8: 4823 + 689 = 5512
Step 9: 5512 + 689 = 6201
Step 10: 6201 + 689 = 6890

So, 689*10 = 6890
