Alright, let's solve this math problem step by step. First, we have the number 715. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 22. So, we're going to take the number 715 and add it to itself 22 times.
Step 1: 0 + 715 = 715
Step 2: 715 + 715 = 1430
Step 3: 1430 + 715 = 2145
Step 4: 2145 + 715 = 2860
Step 5: 2860 + 715 = 3575
Step 6: 3575 + 715 = 4290
Step 7: 4290 + 715 = 5005
Step 8: 5005 + 715 = 5720
Step 9: 5720 + 715 = 6435
Step 10: 6435 + 715 = 7150
Step 11: 7150 + 715 = 7865
Step 12: 7865 + 715 = 8580
Step 13: 8580 + 715 = 9295
Step 14: 9295 + 715 = 10010
Step 15: 10010 + 715 = 10725
Step 16: 10725 + 715 = 11440
Step 17: 11440 + 715 = 12155
Step 18: 12155 + 715 = 12870
Step 19: 12870 + 715 = 13585
Step 20: 13585 + 715 = 14300
Step 21: 14300 + 715 = 15015
Step 22: 15015 + 715 = 15730

So, 715*22 = 15730
