A description of the puzzle and its challenge

Brain Test 66 is one of the most popular puzzles in the game, because it is very tricky and clever. The puzzle shows two equations on a blackboard, followed by an answer box. The equations are:

9 + 4 = 13

5 – 8 = 3

The answer box has three digits, with a question mark on each digit. The puzzle asks you to find the smallest possible number that can be written in this box.

The challenge of this puzzle is that it seems impossible to find a smaller number than zero, which would be written as 000 in the box. However, there is a hidden trick that can help you find an even smaller number. Can you figure it out?

How to solve Brain Test 66?

A step-by-step guide with screenshots and explanations

Step 1: Identify the equation and the answer box

The first step is to identify the equation that you need to use to find the answer. In this case, it is the second equation, 5 – 8 = 3. This equation is obviously wrong, because 5 minus 8 is not equal to 3. This means that there is something wrong with this equation that needs to be fixed.

The second step is to identify the answer box that you need to fill in with the smallest possible number. In this case, it is the box with three question marks. This box can hold any three-digit number, from 000 to 999. However, we are looking for the smallest number, so we need to find a way to make this number as negative as possible.

Step 2: Move the minus sign from the second equation to the answer box

The trick to solving this puzzle is to realize that you can move the minus sign from the second equation to the answer box. To do this, you need to tap and drag the minus sign from the equation to the left side of the box. This will change the box from a positive number to a negative number.

Here is a screenshot of how it looks like after moving the minus sign:

Step 3: Enter -999 as the answer

The final step is to enter -999 as the answer in the box. This is the smallest possible three-digit number that can be written in this box, because it is the most negative number. To enter this number, you need to tap on each question mark and select 9 from the options that appear.

Here is a screenshot of how it looks like after entering -999:

Congratulations, you have solved Brain Test 66!

Why is -999 the answer?

A logical explanation of why this is the smallest possible three-digit number

You might be wondering why -999 is the answer and not -1000 or -1001. The reason is that these numbers are not three-digit numbers, but four-digit numbers. A three-digit number has only three digits, from 0 to 9, in each place value. A four-digit number has four digits, from 0 to 9, in each place value.

For example, -1000 has four digits: one in the thousands place, zero in the hundreds place, zero in the tens place, and zero in the ones place. Similarly, -1001 has four digits: one in the thousands place, zero in the hundreds place, zero in the tens place, and one in the ones place. These numbers are too big to fit in the box that has only three spaces for digits.

Therefore, -999 is the smallest possible three-digit number that can be written in this box, because it has three digits: nine in the hundreds place, nine in the tens place, and nine in the ones place. It is also the most negative number, because it is smaller than any other negative three-digit number, such as -998 or -900.
