# 7 Amazing Tricks of Math 10x Faster | 7tricks

Here are seven tricks for math that are going to be very amazing. These are very easy and simple tricks but are very important in the field of math.

### These are the seven amazing tricks for Math:-

1. Multiply 95 95 etc. in 2 seconds!
2. Multiply 67 9999999 in 5 seconds!
3. Cube root of any no. in 2 seconds!
4. The square root of any complex number!
5. 243 X 567 in 5 seconds!
6. 46 X 82 in 5 seconds!
7. Divisibility Rule Trick!

#### 1. Multiply 95 X 95 etc. in 2 seconds:

Yes, with this trick you can multiply 95X95 or 45X45 or 75X75, etc. in 2 seconds.

For example:- 65X65 = 4225 [First multiply 6 with 7(that is 6+1) we will get 42 and then write 25]
95X95 =  9025 [First multiply 9 with 10(that is 9+1) we will get 90 and then write 25]
45X45 = 2025 [First multiply 4 with 5(that is 4+1) we will get 20 and then write 25]

I hope you get this trick, now you can multiply others similarly. This trick only works for squaring of numbers ending with 5 or which ones is 5.

#### 2.Multiply 167 X 99999 in 5 seconds:

Can you imagine, that you can multiply these types of multiplication in 5 seconds? You can improve your calculation 10x faster with this trick. Follow these steps to learn it-

• Subtract 1 from the first number for example here is 167 then write 166.
• Now subtract 166 from 99999 which will give 99338, you can do it without the help of a notebook.
• That’s it, the answer is 16699338. You can do it in less than 5 seconds.
Let’s take some more examples-
13456X99999 = 1345586544 , it took less than 5 seconds.
Subtract 1 from 13456 and then subtract 13455 from 99999 and write directly.
I hope you get this trick!

#### 3. Cube Root of any Number is 2 seconds:

This is an amazing math trick you can boost your calculation by 10x. You will be able to calculate the cube root of any number in 2 seconds!
Follow these steps to calculate the cube root of any number:-
• For Example, the number is 19683, underline the last three digits and see, it ends with 3 which means 33 = 27.
• Write 7 and now see 19 it is less than 23
• So the final answer is 47.
Let’s take some examples:-
• Cube Root of 250047:- See the last digit it’s 7 so write 3 because 73 ends with 3 i.e. 343. Then look at 250 it’s less than 63  So our final answer is 63.
• Cube Root of 175616:- See the last digit it’s 6 so write 6 because 63 ends with 6 i.e. 216. Then look at 175 it’s less than 53  So our final answer is 56.
I hope now you get this trick.

#### 4. The Square root of any complex number:

A complex no. is an imaginary number. Many questions have been asked in JEE Mains and board of square root of a complex no. We have made a different post for this topic you can learn by clicking here.

#### 5. Multiply 2 digits no. with Short Tricks:

In this trick, you are going to learn how to multiply two-digit numbers quickly:-
(i) AB × CD = AC / AD + BC / BD
Let A, B, C, and D be 4 different numbers then for multiplying AB x CD is equal to multiplication of A & D slash multiplication of A & D and then add this in the multiplication of B & C slash multiplication of B & D.
Let’s Take an example–>
Ex. 35 × 47
= 12 / 21 + 20 / 35
= 12 / 41 / 35

= 1645

(ii) AB × AC = A2 / A (B + C) / BC
If question have first digit same in both numbers that we have to multiply. then solve by this formula!
Ex. 74 × 76
= 72 / 7(4 + 6) / 4 × 6
= 49 / 70 / 24
= 5624
(iii) AB × CC = AC / (A + B)C / BC
Ex. = 35 × 44
= 3×4 / (3+5) × 4 / 5×4
= 12 / 32 / 20
= 1540

#### 6. Multiply 3 digits no. with Short Tricks:

Let, the question given like that ABC × DEF (Here, A, B, C, D, E, F are integers ) then for solving these type of multiplication fast use this formula-
ABC × DEF = AD / AE + BD / AF + BE + CD / BF + CE / CF
Let’s take an example for this—>
Ex. 456 × 234
= 4×2 /4×3 + 5×2/4×4 + 5×3 + 6×2/5×4 + 6×3/6×4
= 8/12 + 10/16 + 15 + 12/20 + 18/24
= 8/22/43/38/24
= 106704
