OK, let's crack this. We're given 288 and our task is to multiply it by 13. Essentially, we'll be adding 288 to itself 13 times.
Step 1: 0 + 288 = 288
Step 2: 288 + 288 = 576
Step 3: 576 + 288 = 864
Step 4: 864 + 288 = 1152
Step 5: 1152 + 288 = 1440
Step 6: 1440 + 288 = 1728
Step 7: 1728 + 288 = 2016
Step 8: 2016 + 288 = 2304
Step 9: 2304 + 288 = 2592
Step 10: 2592 + 288 = 2880
Step 11: 2880 + 288 = 3168
Step 12: 3168 + 288 = 3456
Step 13: 3456 + 288 = 3744

So, 288*13 = 3744
