Alright, let's solve this math problem step by step. First, we have the number 100. 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 100 and add it to itself 35 times.
Step 1: 0 + 100 = 100
Step 2: 100 + 100 = 200
Step 3: 200 + 100 = 300
Step 4: 300 + 100 = 400
Step 5: 400 + 100 = 500
Step 6: 500 + 100 = 600
Step 7: 600 + 100 = 700
Step 8: 700 + 100 = 800
Step 9: 800 + 100 = 900
Step 10: 900 + 100 = 1000
Step 11: 1000 + 100 = 1100
Step 12: 1100 + 100 = 1200
Step 13: 1200 + 100 = 1300
Step 14: 1300 + 100 = 1400
Step 15: 1400 + 100 = 1500
Step 16: 1500 + 100 = 1600
Step 17: 1600 + 100 = 1700
Step 18: 1700 + 100 = 1800
Step 19: 1800 + 100 = 1900
Step 20: 1900 + 100 = 2000
Step 21: 2000 + 100 = 2100
Step 22: 2100 + 100 = 2200
Step 23: 2200 + 100 = 2300
Step 24: 2300 + 100 = 2400
Step 25: 2400 + 100 = 2500
Step 26: 2500 + 100 = 2600
Step 27: 2600 + 100 = 2700
Step 28: 2700 + 100 = 2800
Step 29: 2800 + 100 = 2900
Step 30: 2900 + 100 = 3000
Step 31: 3000 + 100 = 3100
Step 32: 3100 + 100 = 3200
Step 33: 3200 + 100 = 3300
Step 34: 3300 + 100 = 3400
Step 35: 3400 + 100 = 3500

So, 100*35 = 3500
