As you can see, the “=” number is divided into two blocks, you can discover this formula!

The blue portion of the image highlights the numbers after the “=”, along with the numbers obtained by adding up the numbers of the formulas, along with green part of the first half of the image of numbers obtained by subtracting the number of the formulas.

Using X and Y will be used to explain the formula.

If follow this formula, you will be able to solve the problem of “X + Y = 123”

X + Y = 23 and X-Y = 1

Let’s try to solve this as a “simultaneous equation”. When considered in the addition and subtraction method of simultaneous equations, adding the two equations such as **（Ｘ＋Ｘ）（Ｙ－Ｙ）＝（２３＋１）**and

**２Ｘ＝２４**. The formula therefore consists of **Ｘ＝１２**.

**Ｘ－Ｙ＝１** and **Ｘ＝１２**

１２－Ｙ＝１ and Ｙ＝１１

Therefore, the answer is **１２＋１１＝１２３**! If you were able to guess the correct answer then congratulations! **If people with an IQ of 150 actually challenged this problem, they would understand the possibility that this formula is correct!**

**１２＋１１＝１２３** is the answer though some people have claimed there are actually variations to this answer!

The answer looks like the image below!
