Alright, let's solve this math problem step by step. First, we have the number 705. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 25. So, we're going to take the number 705 and add it to itself 25 times.
Step 1: 0 + 705 = 705
Step 2: 705 + 705 = 1410
Step 3: 1410 + 705 = 2115
Step 4: 2115 + 705 = 2820
Step 5: 2820 + 705 = 3525
Step 6: 3525 + 705 = 4230
Step 7: 4230 + 705 = 4935
Step 8: 4935 + 705 = 5640
Step 9: 5640 + 705 = 6345
Step 10: 6345 + 705 = 7050
Step 11: 7050 + 705 = 7755
Step 12: 7755 + 705 = 8460
Step 13: 8460 + 705 = 9165
Step 14: 9165 + 705 = 9870
Step 15: 9870 + 705 = 10575
Step 16: 10575 + 705 = 11280
Step 17: 11280 + 705 = 11985
Step 18: 11985 + 705 = 12690
Step 19: 12690 + 705 = 13395
Step 20: 13395 + 705 = 14100
Step 21: 14100 + 705 = 14805
Step 22: 14805 + 705 = 15510
Step 23: 15510 + 705 = 16215
Step 24: 16215 + 705 = 16920
Step 25: 16920 + 705 = 17625

So, 705*25 = 17625
