# The calculation "8 + 11" controversy

Updated on April 22, 2016

According to the Independent newspaper of Britain, this problem has just been Randall Jones posted on Facebook and in the comment section seems to be confusing people because not sure where is the correct answer, in part, due to the nature of its open answer.

Embarrassment first of all comes from the fact that the addition of "conventional" for this problem have not yet properly and you need to add the math expression to make it right.
To solve apparently you must observe and wonder why such to find answers for the calculation 5 + 10 =?

Obviously not simple type 1 + 1 = 2, maybe we're skipping something. We have two simple workarounds for this puzzle, which was based on the model of classical mathematics award.

Option one:

The first is the user allowed to plus the results of the line immediately above it and so on, basically we are going to have results like this:

1 + 4 = 5

5 + 2 + 5 = 12

12 + 3 + 6 = 21

All are in the right order, i.e. can solve by this method.

At that final calculations will become:

21 + 8 + 10 =?

? = 40

The second variant:

The second assumption is to use the multiplication with two numeric and then plus head.

The result is:

1 + (4x1) = 5

2 + (5x2) = 12

3 + (2 * 3) = 21

Again, the problem still remains true, means this is still true. ...

At that:

8 + (8 * 8) =?

8 + 88 =?

? = 96

There are more than 1 answer?

Based on what you see on the original photo, then given a more precise way the rest of the way.

The models put forward are reasonably addressed the issue by adding the numbers in the relevant operations to increase the value for each time to do the math.

Except when jumping from line 3 + line 8 + 6 to 11, the results brought back different?!

Can ensure that we had missed a few steps in between, in this case, two on there will be an incorrect approach.

For example:

1 + 4 = 5

5 + 2 + 5 = 12

12 + 3 + 6 = 21

21 + 4 + 7 = 32

32 + 5 + 8 = 45

45 + 6 + 9 = 60

60 + 7 + 10 = 77

77 + 8 + 10 =?

? = 96

So if this is the solution then we will have to go back to the second approach.
