OK, let's work through this together. We're starting with 978 and we're going to multiply it by 6, which means we add 978 to itself 6 times.
Step 1: 0 + 978 = 978
Step 2: 978 + 978 = 1956
Step 3: 1956 + 978 = 2934
Step 4: 2934 + 978 = 3912
Step 5: 3912 + 978 = 4890
Step 6: 4890 + 978 = 5868

So, 978*6 = 5868
