Alright, let's solve this math problem step by step. First, we have the number 80. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 16. So, we're going to take the number 80 and add it to itself 16 times.
Step 1: 0 + 80 = 80
Step 2: 80 + 80 = 160
Step 3: 160 + 80 = 240
Step 4: 240 + 80 = 320
Step 5: 320 + 80 = 400
Step 6: 400 + 80 = 480
Step 7: 480 + 80 = 560
Step 8: 560 + 80 = 640
Step 9: 640 + 80 = 720
Step 10: 720 + 80 = 800
Step 11: 800 + 80 = 880
Step 12: 880 + 80 = 960
Step 13: 960 + 80 = 1040
Step 14: 1040 + 80 = 1120
Step 15: 1120 + 80 = 1200
Step 16: 1200 + 80 = 1280

So, 80*16 = 1280
