Brain Out Level 84

Overview

The prompt "A simple question! Make the following equation hold." shows the equation 3 + 5 = 3 in colored digits: a pink 3, a black plus sign, a cyan 5, a black equals sign, and a green 3. The equation is obviously wrong because 3 plus 5 equals 8, not 3. The trick is to move the green 3 on the right side.

• Difficulty: Easy
• Estimated moves: 1

Step-by-Step Solution

1. Read the equation: 3 + 5 = 3. The left side is 8, but the right side shows 3.
2. Press and hold the green 3 on the right side of the equals sign.
3. Drag that green 3 off the screen, or move it far to the right so it is no longer part of the equation.
4. Once the green 3 is removed, the remaining equation reads 3 + 5 = ? and the game automatically accepts the correct sum, turning the right side into 8.
5. The congratulations popup appears with the message "You're right! 3+5=8."

The equation reads 3 + 5 = 3. The right side shows a green 3, which is wrong. The correct sum is 8.

Press and hold the green 3 on the right side. Drag it off the screen. The remaining equation automatically shows 3 + 5 = 8. The level clears.

Drag the green 3 off the right side of the equation. The remaining equation shows 3+5=8 automatically. If you drag the wrong digit, the equation breaks.

Drag the green 3 off the right side. If you drag the wrong digit, the equation breaks. Only the right-side 3 should be removed.

Drag the green 3 off the right side of the equation. The equation then shows 3 plus 5 equals 8 automatically. Do not drag the other digits.

Strategy & Reasoning

The right-side 3 is a draggable decoy. You do not need to type anything; you just need to remove the wrong number. Once the green 3 is gone, the game computes the correct answer 8 and displays it. The colored digits are all movable, but only the rightmost green 3 needs to go. This is a classic "remove the wrong answer" trick.

The green 3 on the right side of the equation is a draggable decoy. Remove it, and the game automatically computes the correct sum 8. You do not need a keyboard or to type anything. The colored digits are all movable, but only the rightmost 3 needs to go.

The right-side green 3 is wrong. Remove it and the game computes 3 plus 5 equals 8. The pink 3 and cyan 5 must stay in place.

Tips & Common Mistakes

• Do not drag the pink 3 on the left. That is the first addend and must stay.
• Do not drag the cyan 5. That is the second addend.
• Do not try to type an 8 on the keypad. There is no keypad; just drag the green 3 away.
