Let's roll up our sleeves and solve this. We have 908 and we're going to multiply it by 7, essentially adding 908 to itself 7 times.
Step 1: 0 + 908 = 908
Step 2: 908 + 908 = 1816
Step 3: 1816 + 908 = 2724
Step 4: 2724 + 908 = 3632
Step 5: 3632 + 908 = 4540
Step 6: 4540 + 908 = 5448
Step 7: 5448 + 908 = 6356

So, 908*7 = 6356
