Quick Calculation Tricks for Lake View Scholars
Math doesn't always need a calculator. Simple tricks can speed up thinking. This helps Lake View scholars solve problems fast. Learning these moves makes math exciting. You can impress your friends and teachers!
Trick 1: Easy Adding and Subtracting
How to add fast? Look for numbers close to 10 or 100. Round them first in your head. Then, you just adjust your answer.
Why use this trick? It makes big numbers seem small. It helps you get answers quickly. You save time.
Example: You buy a new book for $9.95 at a bookstore on Clark Street in Lake View. How much change from $20.00?
- Think $10.00.
- So, $20.00 - $10.00 equals $10.00.
- Add the 0.05 back.
- Your change is $10.05.
- This trick works for bigger numbers, too.
Trick 2: Multiplying by 10, 100, and 1,000
How does this work? Just add zeroes to the end of your number. Add one zero for 10. Add two zeroes for 100.
Why is it useful? This trick is super quick. It saves lots of time multiplying. You get answers instantly.
Example: You have 15 friends visiting the Lincoln Park Zoo. Each friend needs 10 small bags of peanuts. How many bags total?
- Just add a zero to 15.
- That makes 150 bags! (15 x 10 = 150).
Trick 3: Doubling and Halving Numbers
When can you use this? It's great for multiplication. Use it if one number is even. Halve one number. Double the other.
Why does it help? It can turn hard problems into easy ones. It simplifies tricky numbers. You solve it faster.
Example: A souvenir stand outside Wrigley Field sells 14 Cubs hats for $8 each. What is the total cost?
- Halve 14 (which is 7).
- Double 8 (which is 16).
- Now, multiply 7 x 16.
- This makes it 112. (14 x 8 = 112).
Trick 4: Multiplying by 5
How to multiply by 5 easily? Multiply your number by 10 first. Then, cut that answer in half.
Why is this helpful? It’s faster than counting by 5s. You don't need a calculator. It’s a handy trick.
Example: You walk 12 blocks down Broadway Street in Lake View. Each block takes 5 minutes to walk. How much time total?
- Multiply 12 by 10, getting 120.
- Now cut 120 in half (because 5 is half of 10).
- That is 60 minutes. (12 x 5 = 60).
