Let’s face it, math can be hard. Numbers can get confusing, and whether you enjoy math or not, sometimes you need a little extra help. Here are three super helpful tips for making math easier:
6 times tables: The six times tables can seem unpatterned and complicated, but with this simple trick, they’ll all be easy. When you multiply a number by six, the last digit of your answer is going to be the same as the number you’re multiplying by six, and the first digit is that number divided by two.
For example: For 4×6, the first digit of the solution is 4÷2, or 2, and the second digit is just 4: therefore, 6×4=24
Percentages: Some percentages are far easier to find than others, and you can actually use the easier ones to figure out the harder ones! Percentages are reversible, meaning that you can switch the number you’re trying to find the percent of and the percentage value.
For example: 16% of 50 is the same as 50% of 16: to take 50% of 16, you simply divide 16 by 2 to get 8, and there’s your answer! Because 50% of 16 is 8, 16% of 50 is also 8.
Doubling: Doubling big numbers is sometimes intimidating, but luckily, there’s a pretty easy way to do it. All you need to do is double each part of the number separately, and then add it all together.
For example: To double the number 372, break it apart into 300, 70, and 2. Then, double each part of that to get 600, 140, and 4. Finally, add these three numbers together to get 744.
We hope these tricks help you out. Good luck with exams, and let us know what other tricks you know!
