Startegy 2 - Plugging in Answer Options Plug in – 4 and – 5 one by one. You'll see –4 works perfectly. That’s in Option B. You’re done.

How to Eliminate Like a Pro? Step 1: Spot big numbers Option A has 20 → If you plug that in: 20(3×20 + 7) → that’s clearly huge, not 20. ❌ Eliminate A Option C has 4 → 4(3×4 + 7) = 4×19 = 76 ❌ way too big. Eliminate C Now only B and D remain. What do we do next?

ISEE Question of the Day If you know how to solve this — do you know how to solve it fast?
ISEE Summer Smarts! Stop crunching numbers. Start thinking smart. Pair wisely: (3 × 5) = 15, (4 × 6) = 24 → Column A becomes 15 × 24 Both columns start with 15, but 24 > 21. No calc. No full multiply. Just clever grouping. Train for strategy #ISEEprep

ISEE Question of the Day! Column A: 3 × 4 × 5 × 6 Column B: 15 × 21 A. Column A is greater B. Column B is greater C. The two quantities are equal D. The relationship cannot be determined How do you solve it quick—some mental math or no calc at all? 🧠 Drop your method below!
ISEE Pro Tip!
Here's how to approach this - ISEE style! Ans: Mean and Median remain equal!

ISEE Question of the Day A data set of 9 numbers has mean 12 and median 12. Two numbers, 3 and 21, are added. Which is greater? (a) Mean of the new data set (b) Median of the new data set (a), (b), or equal? Think carefully! Quote tweet with your reasoning.
Rather than counting, use symmetry: The top and bottom rows have the same number of values → ignore them. Do the same for the rows 2 & 4. You’re left with the middle row: Now you can count or simply cross out values from the ends inward: You're left with 4, thus median = 64.

ISEE Question of the Day Check out the stem-and-leaf plot 👇 What’s the median of this data set? Drop your answer + how would you solved it fast! ⏱ #ISEEprep #MathChallenge #DataSkills
Do we list all primes in each range? Not at all! We draw it out -> 🎯 Use the Number Line Trick: 15–25: (B) has 3 primes → 17, 19, 23 45–55: (A) has 2 primes → 47, 53 Common part (25–45) cancels out. ➡️ (B) wins by 1 prime. Quick & clean! #ISEEprep #MathHack
ISEE Question of the Day Here’s one to test your number sense. How would you solve it — not just correctly, but fast? #MathChallenge #ISEEprep
