OK, let's crack this. We're given 314 and our task is to multiply it by 10. Essentially, we'll be adding 314 to itself 10 times.
Step 1: 0 + 314 = 314
Step 2: 314 + 314 = 628
Step 3: 628 + 314 = 942
Step 4: 942 + 314 = 1256
Step 5: 1256 + 314 = 1570
Step 6: 1570 + 314 = 1884
Step 7: 1884 + 314 = 2198
Step 8: 2198 + 314 = 2512
Step 9: 2512 + 314 = 2826
Step 10: 2826 + 314 = 3140

So, 314*10 = 3140
