Here are the ten math tactics that will amaze you and friends. Memorize and practice these tricks, and you’ll find math problems a piece of cake.

1)
Adding two-digit numbers left to right

If you want to calculate the sum of two 2-digit numbers, try this method. It also makes it easy to calculate sums in your head. Here we’ll calculate the sum of 84 and 96.

84 + 96 =

• Add numbers on tens place and write answer with second digit of first number. 84 + 94 = 174

• Add the second digit of second number to sum. 174 + 6 = 180.

84 + 96 = 180

2) Subtracting a number from 1000

If you want to subtract 554 from 1000, follow these steps:

• Subtract each digit from nine, except the last digit, which you subtract from ten.
• Subtract 5 from 9 → 4
• Subtract 5 from 9 → 4
• Subtract 4 from 10 → 6

The answer is 446.

3) Multiplying an even number by 5

Multiplying a large number by five can be difficult sometimes. This trick will help you solve the multiplication without using any calculating device. Keep in mind that there are two types of numbers, odd and even. So this trick will be different for both odd and even numbers.

For example, you want to multiply 46 by 5. Follow these steps to solve it:

46 x 5 =

• Cut the number being multiplied by five into halves. Or you can divide the number by 2. So, the half of 46 is 23

• Add a zero to the number we found. In this way, the 23 becomes 230. That is the answer of 46 multiplied by 5.

4) Multiplying an odd number by five

If you want to multiply 29 by 5, you can solve it as:

29 x 5 =

• Subtract one from the number getting multiplied. By subtracting one from twenty-nine, we get 28.
• Now, cut this number in half or divide by 2. The twenty-eight will become 14. Write down five at the end of the number. It means the 14 will get written as 145. It is the answer.

29 x 5 = 145

5) Division shortcuts

To determine whether a number can be divided evenly:

• A number is divisible by ten if it ends in 0.

• A number ending in 0 or 5 gets divided by 5.

• A number ending in an even number is divisible by 2.

• A number is divisible by three if the sum of its digits is divisible by 3. For example, 39 is divisible by three because 3 + 9 = 12, and 12 is divisible by 3.

6) Calculating 5% of a number

To get 5% of any number, like 253, follow these steps:

5% of 253

• Move the decimal point one place to the left → 25.3
• Divide by 2 → 25.3 ÷ 2 = 12.65

5% of 253 = 12.65

7) Multiplying large numbers

Multiplying large numbers can be very tricky. Follow these steps to multiply large numbers.

For example, you want to multiply 40 and 260.

Multiply 40 and 260

• Divide the first number by two to get its half. So forty will become twenty.

• Double the second number. So, 260 will become 520.

• Multiply the transformed numbers: 20 × 520 = 10,400, which is also the answer to the actual question.

40 x 260 = 10400

8) Squaring a two-digit number

Squaring a number can be difficult sometimes. Try this shortcut for getting a square of a two-digit number like 46.

Square of 46

• Add the last digit of the number to the whole number itself. 46 + 6 = 52.

• Multiply 52 by the first digit of the original number: 52 × 4 = 208. Then square the last digit of the original number: 6² = 36.

• Append the result of the last step (36) to 208 to get 2116.

Square of 46 = 2116

9) Squaring a two-digit number ending in 5

For instance, you want to calculate the square of 45, follow these steps:

Square of 45

• Multiply the first digit by itself and add one to it. So, the answer of [ 4 ( 4 + 1) ] will be 20.

• Now put 25 at the end, and it will become 2025. So, this is also the square of the original digit 45.

Square of 45 = 2025

10) Memorizing the value of pi

Pi plays a most significant role in math. Calculations related to volumes, areas, radii, and circumferences involve pi. We know that pi equals 22/7 as a fraction. But in decimal numbers, we forget the exact value. You can remember the value of the first seven digits of the decimal fraction of pi by memorizing this line:

“How I wish I could calculate pi.”

Calculate how many letters there are in every word of this line. And that will give you the digits of pi.

3.141592 is the value of pi.

Conclusion

These tricks help you solve problems quickly and with less chance of making mistakes. You can use them in different areas of math, such as algebra and geometry. What’s cool is that these tricks are actually pretty clever and straightforward. As you practice these tricks, you’ll find that math problems aren’t as tricky as they seemed before. So, give them a try, and you’ll see that math can be a cool adventure!
