Alright, let's solve this math problem step by step. First, we have the number 850. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 29. So, we're going to take the number 850 and add it to itself 29 times.
Step 1: 0 + 850 = 850
Step 2: 850 + 850 = 1700
Step 3: 1700 + 850 = 2550
Step 4: 2550 + 850 = 3400
Step 5: 3400 + 850 = 4250
Step 6: 4250 + 850 = 5100
Step 7: 5100 + 850 = 5950
Step 8: 5950 + 850 = 6800
Step 9: 6800 + 850 = 7650
Step 10: 7650 + 850 = 8500
Step 11: 8500 + 850 = 9350
Step 12: 9350 + 850 = 10200
Step 13: 10200 + 850 = 11050
Step 14: 11050 + 850 = 11900
Step 15: 11900 + 850 = 12750
Step 16: 12750 + 850 = 13600
Step 17: 13600 + 850 = 14450
Step 18: 14450 + 850 = 15300
Step 19: 15300 + 850 = 16150
Step 20: 16150 + 850 = 17000
Step 21: 17000 + 850 = 17850
Step 22: 17850 + 850 = 18700
Step 23: 18700 + 850 = 19550
Step 24: 19550 + 850 = 20400
Step 25: 20400 + 850 = 21250
Step 26: 21250 + 850 = 22100
Step 27: 22100 + 850 = 22950
Step 28: 22950 + 850 = 23800
Step 29: 23800 + 850 = 24650

So, 850*29 = 24650
