Personally, I love math but it wasn’t always that way and I use to dread math puzzles in school. Math is formally taught using tried and true principles of Common Core but these math tricks and hacks will help provide tips to better solve those math problems.
Whether we realize it or not, we solve math problems on a daily basis. Whether it’s at a restaurant when calculating a tip or when out shopping and totaling our items or taxes, it helps when we could quickly crunch these numbers using our minds instead of a calculator.
1) Math tricks for adding and subtracting fractions using the Butterfly method.
“Butterfly method for adding and subtracting fractions!”
2) Remember “Which Sign Is Greater Than and Which Is Less Than?” The alligator always eats the larger value.
3) Math tricks for figuring out percentages using this easy formula.
“When trying to look for percentages (example: 40% of 300) drop the 1s digit of the number and multiply by the 10s digit of the % (4 x 30 = 120).”
4) Remember the full value of pi using an easy-to-remember sentence.
“You can remember the value of pi (3.1415926) by counting each word’s letter in ‘May I have a large container of coffee?'”
5) Multiply any number by 11 using only 2 steps with these math tricks.
6) Multiply large numbers in your head.
7) Find fractions of whole numbers using this technique.
“Reverse Zorro! Starting at the bottom, draw a line from the 4 to the 24 (4 goes into 24 six times). Draw the line to the 3 (six times three is 18). Draw the top line and write the answer.”
8) Converting Fahrenheit to Celsius is super easy.
“C to F: Multiply the temperature by 2 and then add 30 (the actual formula is to multiply by 1.8, add 32) Example: 22 C is roughly equal to 74 degrees; actual conversion is 71.6. F to C: Now just work it backward, subtract 30 from the temp. and then divide by 2.”
9) Figure Out Multiples Of Nine. What the teachers never taught us…
10) How To Use Your Hands For 5, 6, and 9 Times Tables.
“The tables of 6, 7, 8, and 9 are in your hands. Count the fingers. Count and multiply. Here are all the steps for using your hands for 5, 6, and 9 times tables.”
Some of these math tricks are tricky at first but once mastered, they’ll provide excellent techniques for solving complex math equations.
