OK, let's crack this. We're given 214 and our task is to multiply it by 16. Essentially, we'll be adding 214 to itself 16 times.
Step 1: 0 + 214 = 214
Step 2: 214 + 214 = 428
Step 3: 428 + 214 = 642
Step 4: 642 + 214 = 856
Step 5: 856 + 214 = 1070
Step 6: 1070 + 214 = 1284
Step 7: 1284 + 214 = 1498
Step 8: 1498 + 214 = 1712
Step 9: 1712 + 214 = 1926
Step 10: 1926 + 214 = 2140
Step 11: 2140 + 214 = 2354
Step 12: 2354 + 214 = 2568
Step 13: 2568 + 214 = 2782
Step 14: 2782 + 214 = 2996
Step 15: 2996 + 214 = 3210
Step 16: 3210 + 214 = 3424

So, 214*16 = 3424
