Brain Blow Level 48
📝 Walkthrough
Overview
An equation shows R equals P on the board, and the prompt asks you to correct the equation. The right side already reads P, while the left letter R has an extra diagonal leg that makes it differ from P. Rubbing or erasing that extra leg turns the R into a P, leaving P equals P as a correct equation. No number or symbol needs to be moved, only the extra stroke of the letter removed.

Step-by-Step Solution
- Read the equation and compare the two letters: the right side is P, and the left side is R, which shares P's vertical stem and bowl but adds a diagonal leg.
- Identify the extra diagonal leg on the R that distinguishes it from a P. This stroke is the part that must be removed to match the right letter.
- Rub or erase that diagonal leg off the R, rubbing it away until only the vertical stem and bowl remain, forming a clean P.
- Check that the corrected left letter now reads P, so the equation shows P equals P and balances. The level completes once the erasure fixes the letter pair.
- Rub the diagonal leg of the R gently until it disappears, leaving the vertical stem and the rounded bowl intact, so the result reads as a clean P rather than a half-erased mark. Compare the corrected left letter against the P on the right side of the equals sign, and make sure no leftover stroke still crosses the bowl. Once both sides show the same P, the equation balances, and the erasure is complete without any letter being moved or swapped.
- The right side of the equation already shows the target letter P, so it acts as the reference for the corrected left letter. Removing the diagonal leg leaves that matching P in place, and the balanced P equals P statement is what the level recognizes as the fixed equation.
Strategy & Reasoning
Equation-correction levels often ask you to remove a pen stroke rather than rearrange numbers. Here the mismatch is a letter shape, and R differs from P by one diagonal leg, which is the removable detail. Wiping that leg off turns the left character into the same letter as the right side.
Because the right side already shows the target letter P, it serves as the reference for what the left letter should become. The bowl and stem of the R already match a P, so deleting the diagonal leg completes the transformation without redrawing the whole character. Once both sides read P, the equality holds and the level recognizes the correction.
Tips & Common Mistakes
- Rub only the extra diagonal leg of the R; the stem and bowl stay, because those parts already match the P on the right.
- Do not move or swap any symbol in the equation; the fix is removing one stroke, not rearranging the letters.
- Finish once the left letter looks identical to the P on the right, so the two sides read the same letter.
