Alright, let's solve this math problem step by step. First, we have the number 215. 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 215 and add it to itself 35 times.
Step 1: 0 + 215 = 215
Step 2: 215 + 215 = 430
Step 3: 430 + 215 = 645
Step 4: 645 + 215 = 860
Step 5: 860 + 215 = 1075
Step 6: 1075 + 215 = 1290
Step 7: 1290 + 215 = 1505
Step 8: 1505 + 215 = 1720
Step 9: 1720 + 215 = 1935
Step 10: 1935 + 215 = 2150
Step 11: 2150 + 215 = 2365
Step 12: 2365 + 215 = 2580
Step 13: 2580 + 215 = 2795
Step 14: 2795 + 215 = 3010
Step 15: 3010 + 215 = 3225
Step 16: 3225 + 215 = 3440
Step 17: 3440 + 215 = 3655
Step 18: 3655 + 215 = 3870
Step 19: 3870 + 215 = 4085
Step 20: 4085 + 215 = 4300
Step 21: 4300 + 215 = 4515
Step 22: 4515 + 215 = 4730
Step 23: 4730 + 215 = 4945
Step 24: 4945 + 215 = 5160
Step 25: 5160 + 215 = 5375
Step 26: 5375 + 215 = 5590
Step 27: 5590 + 215 = 5805
Step 28: 5805 + 215 = 6020
Step 29: 6020 + 215 = 6235
Step 30: 6235 + 215 = 6450
Step 31: 6450 + 215 = 6665
Step 32: 6665 + 215 = 6880
Step 33: 6880 + 215 = 7095
Step 34: 7095 + 215 = 7310
Step 35: 7310 + 215 = 7525

So, 215*35 = 7525
