OK, let's work through this together. We're starting with 608 and we're going to multiply it by 9, which means we add 608 to itself 9 times.
Step 1: 0 + 608 = 608
Step 2: 608 + 608 = 1216
Step 3: 1216 + 608 = 1824
Step 4: 1824 + 608 = 2432
Step 5: 2432 + 608 = 3040
Step 6: 3040 + 608 = 3648
Step 7: 3648 + 608 = 4256
Step 8: 4256 + 608 = 4864
Step 9: 4864 + 608 = 5472

So, 608*9 = 5472
