Brain Blow Level 36

Overview

An equation appears on the board: 7.5 minus 6 plus 0.5, with a result field beside the equals sign. The prompt asks whether you can solve the equation. The arithmetic is ordinary addition and subtraction once the decimals are treated as written, and no object needs to be dragged or rearranged. Working through the terms gives the result 2, which fills the result field and completes the level.

• Difficulty: Easy
• Estimated moves: 1

Step-by-Step Solution

1. Read the equation carefully: 7.5 minus 6 plus 0.5, written left to right with no brackets. Identify each number and its operator before computing.

1. Perform the subtraction first: 7.5 minus 6 leaves 1.5. Keep this intermediate result in mind before applying the remaining operator.

1. Add the final 0.5 to the 1.5, which brings the total to 2. Confirm the decimal handling so no half-unit is lost between the two steps.

1. Enter 2 into the result field beside the equals sign. The level completes once the calculated total matches the expected answer, and there is no hidden rearrangement of the digits required.

1. Keep the terms in their written order and do not swap the minus and plus signs, since the equation has no brackets that would change the grouping. If the intermediate 1.5 feels awkward, write the two halves out separately: the 7.5 contributes a half, subtracting 6 leaves that half, and adding the second half completes the whole 2. Enter this result directly, and resist looking for a digit to erase or move, since this level expects plain arithmetic.

1. The result field takes the computed whole number 2, and there are no multiple-choice cards to match it against. Recheck the decimal addition once more if the entry feels uncertain, then submit the result directly, since this arithmetic level has no hidden object or gesture to perform.

Strategy & Reasoning

Some equation levels are solved by moving or erasing digits, but this one reads as a straightforward arithmetic expression. The decimals split cleanly: subtracting 6 from 7.5 leaves a half, and adding the other half rounds that intermediate value up to a whole number. No trick changes the meaning of the signs.

Because the operators alternate between minus and plus, working left to right keeps the computation simple and avoids reordering the terms. The result 2 balances the equation, and entering it directly finishes the level. This level is a brief arithmetic break between the gesture and drag puzzles that surround it.

Tips & Common Mistakes

• Do not look for a digit to move or erase; this equation solves with normal arithmetic rather than a shape trick.
• Keep the decimal halves in mind: subtracting 6 leaves 1.5 before the final 0.5 is added, so the result is a whole 2.
• Enter the calculated total into the result field; no multiple-choice buttons appear here, only the computed value matches the equation.
