Here are some tips and tricks for elementary-level Math classes. These come from expert elementary math tutors.
Multiplying a Number by 5
Need to multiply a number by 5? Don’t. Instead, divide the number by 2 and multiply the result by 10. It will be an easier calculation and you will have your answer in a jiffy. Let’s take an example. Say we need to multiply 46 by 5.
So, 46/2 = 23. Now, 23x10 = 230. And that’s the answer. Easy, right!
Multiplying a Number by 9
Just like the above trick, here is an easy way to multiply a number by 9. This rule applies to single-digit multiplication only. Here’s how it goes.
Say you need to multiply 8 with 9. First, you do 8-1=7. 7 is the first digit of the answer. Then you do 10-8=2. 2 is the second digit of your answer. So, the final answer is 72.
The formula for this trick is; you need to subtract 1 from the number that needs to be multiplied by 9. It gives you the first digit of the answer. Then the next step is to subtract the number from 10. It gives you the second digit. Read that again, don’t get confused. Ask your virtual maths tutors to give you practice questions.
Multiplying Numbers with 0 at the End
Multiplying numbers with a lot of 0s at the tail can get confusing by the traditional method. So, here is a trick that can save the day and solve the question in just a few seconds. Let’s understand this with an example.
Say we have to calculate 400x60. To find the answer simply multiply 4 with 6. Write the answer and follow it up with all the 0’s after 4 and 6. In this case 4x6=24. There are two 0’s after 4 and one after 6, a total of three 0’s. So, the final answer is 24000.
Math can be fun if you know such tricks and tips. But along with these tricks, you also need to focus on the basics. You should learn the tables and most importantly ask for help when needed.
