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 35. So, we're going to take the number 80 and add it to itself 35 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
Step 17: 1280 + 80 = 1360
Step 18: 1360 + 80 = 1440
Step 19: 1440 + 80 = 1520
Step 20: 1520 + 80 = 1600
Step 21: 1600 + 80 = 1680
Step 22: 1680 + 80 = 1760
Step 23: 1760 + 80 = 1840
Step 24: 1840 + 80 = 1920
Step 25: 1920 + 80 = 2000
Step 26: 2000 + 80 = 2080
Step 27: 2080 + 80 = 2160
Step 28: 2160 + 80 = 2240
Step 29: 2240 + 80 = 2320
Step 30: 2320 + 80 = 2400
Step 31: 2400 + 80 = 2480
Step 32: 2480 + 80 = 2560
Step 33: 2560 + 80 = 2640
Step 34: 2640 + 80 = 2720
Step 35: 2720 + 80 = 2800

So, 80*35 = 2800
