Did You Know the 1089 Number Trick?
There’s a maths trick that always ends in 1089, no matter what number you start with (as long as you follow one rule).
Here’s how it works:
1️⃣ Pick any 3-digit number where the first digit is bigger than the last. Example: 732
2️⃣ Reverse the number → 237
3️⃣ Subtract the smaller number from the bigger one → 732 − 237 = 495
4️⃣ Reverse your new number → 594
5️⃣ Add the new number and the result of your subtraction together → 495 + 594 = 1089
And just like that… you get 1089. It works every single time. Try it with a different number and watch the magic happen.

Q232: A laptop costs $33.45 per month on a 12-month payment plan.
James only has $20 per month available from his income, so he decides to save $20 each month before purchasing the laptop on the $33.45 payment plan. He plans to use this savings to cover the difference between $20 and $33.45 each month during the 12-month repayment period.
How many months will James need to save before he can purchase the laptop and still afford all 12 monthly payments?

Did You Know the Sneaky Consecutive Numbers Trick
If you multiply any three consecutive numbers, the answer will always be divisible by 6.
Example:
4 × 5 × 6 = 120
And 120 ÷ 6 = 20
100 × 101 × 102 = 1,030,200
And 1,030,200 ÷ 6 = 171,700
