OK, let's crack this. We're given 265 and our task is to multiply it by 16. Essentially, we'll be adding 265 to itself 16 times.
Step 1: 0 + 265 = 265
Step 2: 265 + 265 = 530
Step 3: 530 + 265 = 795
Step 4: 795 + 265 = 1060
Step 5: 1060 + 265 = 1325
Step 6: 1325 + 265 = 1590
Step 7: 1590 + 265 = 1855
Step 8: 1855 + 265 = 2120
Step 9: 2120 + 265 = 2385
Step 10: 2385 + 265 = 2650
Step 11: 2650 + 265 = 2915
Step 12: 2915 + 265 = 3180
Step 13: 3180 + 265 = 3445
Step 14: 3445 + 265 = 3710
Step 15: 3710 + 265 = 3975
Step 16: 3975 + 265 = 4240

So, 265*16 = 4240
