Alright, let's solve this math problem step by step. First, we have the number 352. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 15. So, we're going to take the number 352 and add it to itself 15 times.
Step 1: 0 + 352 = 352
Step 2: 352 + 352 = 704
Step 3: 704 + 352 = 1056
Step 4: 1056 + 352 = 1408
Step 5: 1408 + 352 = 1760
Step 6: 1760 + 352 = 2112
Step 7: 2112 + 352 = 2464
Step 8: 2464 + 352 = 2816
Step 9: 2816 + 352 = 3168
Step 10: 3168 + 352 = 3520
Step 11: 3520 + 352 = 3872
Step 12: 3872 + 352 = 4224
Step 13: 4224 + 352 = 4576
Step 14: 4576 + 352 = 4928
Step 15: 4928 + 352 = 5280

So, 352*15 = 5280
