Alright, let's solve this math problem step by step. First, we have the number 720. 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 720 and add it to itself 10 times.
Step 1: 0 + 720 = 720
Step 2: 720 + 720 = 1440
Step 3: 1440 + 720 = 2160
Step 4: 2160 + 720 = 2880
Step 5: 2880 + 720 = 3600
Step 6: 3600 + 720 = 4320
Step 7: 4320 + 720 = 5040
Step 8: 5040 + 720 = 5760
Step 9: 5760 + 720 = 6480
Step 10: 6480 + 720 = 7200

So, 720*10 = 7200
