OK, let's work through this together. We're starting with 918 and we're going to multiply it by 8, which means we add 918 to itself 8 times.
Step 1: 0 + 918 = 918
Step 2: 918 + 918 = 1836
Step 3: 1836 + 918 = 2754
Step 4: 2754 + 918 = 3672
Step 5: 3672 + 918 = 4590
Step 6: 4590 + 918 = 5508
Step 7: 5508 + 918 = 6426
Step 8: 6426 + 918 = 7344

So, 918*8 = 7344
