10 MATHS TRICKS
to do math quickly
Here are 10 quick math strategies (adults can use!)
To do math in their minds. Once
these strategies are mastered, students must be able to solve math problems with accuracy and
confidence they were afraid to solve.
MATHS
TRICKS 1st Formula Add large numbers
It can be difficult to add large numbers in your head. This method
describes how to simplify this process by making all numbers be multiple than
10. This is an example:
644 + 238
Although these numbers are difficult to meet,
bringing them closer will make them more manageable. Therefore, 644 becomes 650
and 238 becomes 240.
Now, add 650 and 240 together. The total is 890. To
find an answer to the original equation, you must determine how much we have
added to the numbers to approximate.
650 - 644 = 6 and 240 - 238 = 2
Now, add 6 & 2 together for a total of =8
To find an answer to the original equation, you must
subtract 8 from 890.
890 - 8 = 882
So the answer to 644 + 238 is as we know 882.
MATHS
TRICKS 2nd Formula Subtraction of 1000
Here is a basic rule for subtracting a large number
of 1000: subtract each number, except the latter of 9, and subtract the final
number of 10
For
example:
1000 - 556
Step
1:
subtract 5 from 9 = 4
Step
2:
Subtract 5 from 9 = 4
Step
3:
Subtract 6 from 10 = 4
The answer is 444.
MATHS
TRICKS 3rd Formula Multiplying any number 5 times
When the number 5 is multiplied by an even number,
there is a quick way to find the answer.
For example, 5 × 4 =
Step
1:
Take the number multiplied by 5 and cut it in half, making figure 4 become
number 2.
Step
2:
Add a zero to the number to find the answer. In this case, the answer is 20.
5 x 4 = 20
When you multiply an odd number 5 times, the formula
is slightly different.
For example, consider 5 × 3.
Step
1:
subtract one from the number multiplied by 5, in which case the number 3
becomes the number 2.
Step
2:
Now reduce the number 2, doing it 1. Make 5 the last number. The resulting
figure is 15, which is the answer.
5 x 3 = 15
MATHS
TRICKS 4th Formula Division Section tricks.
Here is a quick way to see when the number can be
divided equally by these specific numbers:
10 if the number ends with 0
9 When adding numbers, the sum is divisible by 9
8 if the last three digits are divisible by 8 or 000
6 If the number is a pair and when the numbers are
added together, the answer is divisible by 3
5 if it ends with 0 or 5
4 If it ends in 00 or in a two-digit number and is
divisible by 4
3 when the numbers are added together and the result
is equally divisible by 3
2 on the off chance that it finishes in 0, 2, 4, 6
or 8
MATHS
TRICKS 5th Formula Multiplying Hit by 9
This is an easy and useful way to hit any number in
9. Here's how it works:
We are going to use a 9 × 3 example.
Step
1:
Subtract 1 from the number multiplied by 9.
3 - 1 = 2
Figure 2 is the first number in the equation.
Step
2:
Subtract this number from the number 9.
9 - 2 = 7
Figure 7 is the second number in the equation.
Therefore, 9 × 3 = 27
MATHS
TRICKS 6th Formula Tricks of
10 and 11 times.
The trick is to hit any number in 10 by adding a
zero to the end of the number. For example, 62 x 10 = 620.
There is also an easy trick to reach any two-digit
number in 11. Here it is:
11 x 25
Take the original two-digit number and place a space
between the numbers. In this example, this number is 25.
2_5
Now add these two numbers and put the result in the
middle:
2_ (2 + 5) _5
2_7_5
The answer to 11 × 25 is 275.
If the numbers in the center add a two-digit number,
enter the second number and add 1 to the first number. The following is an
example of the 11 × 88 equation
8_ (8 + 8) _8
(8 + 1) _6_8
9_6_8
There is a response to 11 × 88: 968.
MATHS
TRICKS 7th Formula Percentage
Finding a percentage of numbers can be quite
difficult, but thinking in the right terms makes understanding much easier. For
example, to see what is 5% of 235, follow this method:
Step
1:
Move the decimal point to a place, 235 becomes 23.5.
Step
2:
Section 23.5 In number 2, the answer is 11.75. This is also the answer to the
original equation.
MATHS
TRICKS 8th Formula Place a
number in a two-digit NUMBERS that ends
in 5
Let's use the number 35 as an example.
Step
1:
First, multiply the number plus 1.
Step
2:
Place the 25 at the end.
35 squared = [3 × (3 + 1)] and 25
[3 × (3 + 1)] = 12
12 and 25 = 1225
Squared =
MATHS
TRICKS 9th Formula multiplication
When multiplying large numbers, if one of the
numbers is equal, divide the first number in half, then multiply the second
digit. This method will solve the problem quickly. For example, consider
20 x 120
Step
1:
Section 20 in 2, equivalent to 10. Double 120, that is, 240.
Then hit your answer together.
10 × 240 = 2400
The answer to 20 × 120 is 2400.
MATHS
TRICKS 10th Formula Multiplying the
numbers that end in zero.
Multiplying the numbers that end in zero is actually
very simple. It involves pasting the other numbers and then adding the zeros at
the end. For example, keep in mind:
200 x 400
Step
1:
Hit 2 times in 4
2 x 4 = 8
Step
2:
Place the four zeros after the number 8.
80000
200 x 400 = 80,000
Practicing these quick MATHS TRICKS can help both students and teachers improve their math skills and you can become a top 1 MATHEMAGICIAN and are confident in
their mathematical knowledge, and
not be afraid to work with numbers in the future. For more learn previous chapters.
