Let's get this math done. We have 845 and we're going to multiply it by 6. This is the same as taking 845 and adding it to itself 6 times.
Step 1: 0 + 845 = 845
Step 2: 845 + 845 = 1690
Step 3: 1690 + 845 = 2535
Step 4: 2535 + 845 = 3380
Step 5: 3380 + 845 = 4225
Step 6: 4225 + 845 = 5070

So, 845*6 = 5070
