OK, let's crack this. We're given 352 and our task is to multiply it by 10. Essentially, we'll be adding 352 to itself 10 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

So, 352*10 = 3520
