Cheat Sheet

  1. Apply Order of Operations (PEMDAS) -

    Mastering PEMDAS ensures you tackle each math quiz or quick math test problem correctly by handling Parentheses, Exponents, Multiplication and Division (left to right), then Addition and Subtraction (left to right). For example, 8 + 4 × 2 = 8 + (4 × 2) = 16, not (8 + 4) × 2 = 24. A handy mnemonic is "Please Excuse My Dear Aunt Sally," widely used in academic courses to keep you on track.

  2. Use the '11' Multiplication Shortcut -

    For any two-digit number ab, multiplying by 11 is as simple as adding those digits between them: 11 × 34 becomes 3 (3+4) 4 = 374. If the sum exceeds 9, carry over to the hundreds place - e.g., 11 × 59 = 5 (5+9=14) 9 = 649. This lightning-fast trick is featured in many university brain math challenge workshops.

  3. Find the Least Common Denominator (LCD) for Fractions -

    Quickly adding or subtracting fractions hinges on the LCD; for 1/3 + 1/4, convert to 4/12 + 3/12 = 7/12. Identifying the LCD by prime factorization - like 3 and 4 becoming 2^2·3 - streamlines the process. University-level algebra courses often reinforce this approach to build confident mental math test skills.

  4. Break Down Percentages into 10%, 5% and 1% -

    Calculating percentages in a math quiz is fastest when you split them: to find 18% of 250, compute 10% (25), 5% (12.5) and 3% (7.5 by adding three 1% chunks, each 2.5), then sum to 45. This stepwise method is endorsed by many maths departments for quick maths test efficiency. Memorizing these chunks boosts speed and accuracy.

  5. Estimation and Rounding for Quick Calculations -

    When facing a brain math challenge under time pressure, round to the nearest 10 or 100 - e.g., 57 + 89 becomes 60 + 90 ≈ 150 - then adjust for the difference (-3 and -1) to get the exact 146. This technique, used in top-tier mental math test prep, keeps you both fast and precise. Practicing estimation cultivates number sense and confidence.
