Question

Albert thought of a number, added 5, multiplied the result by 2, took away 6 and then divided by 2 to give an answer of 8

Answer 1

the answer is 6 ....you just have to do the steps backwards and it will result faster.
6+5=11
11*2=22
22-6=16
16/2=8

Answer 2

To find Albert's original number we have to work backwards. So everything albert did we have to do the reverse.

Starting with 8:

8*2 = 16 + 6 = 22/2 = 11- 5 = 6

Now, lets check it and start from the beginning with this new number (6), and follow everything Albert did and we will get 8. 

6+5= 11*2= 22-6 = 16/2 = 8
