OK, let's crack this. We're given 288 and our task is to multiply it by 7. Essentially, we'll be adding 288 to itself 7 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

So, 288*7 = 2016
