Fast ways to do math:


Many mathematical experts provides us the easy fast ways to learn maths, in the following parts we will see some of the fast ways to do math problems,

Fast ways to do math multiplication of the two digit numbers using 11:

For a two digit number that multiplies with 11, follow the steps for fast multiplication,

For example: Take the number 45

45 * 11

Consider the number 45.
Add 4 +5 = 9
Now insert the 9 inbetween the 4 and 5, gives 495.
We got the final answer 495 fastly using this ways.

Another example:

Take the number 25

25 * 11

Consider the number 25.
Add 2 +5 = 7
Now insert the 7 inbetween the 2 and 5, gives 275.
We got the final answer 275 fastly using this ways.


Fast ways to do math multiplication of the two digit numbers using 16:


For a two digit number that multiplies with 16, follow the steps for fast multiplication,

For example: Take the number 44

44 * 16

Consider the number 44.
Multiply the given number with 10 gives 44*10 = 440.
Then take the half value of the given number, and multiply with 10.
Gives (44 * 1 /2  ) * 10

= 22 * 10

= 220

Now add all the computed terms in above steps with the given number,
= 440 + 220 + 44

= 704

Thus we got the answer as fast as possible using this ways.

We got the final answer 495 fastly.

Another example:

Take the number 64

64 * 16

Consider the number 64.
Multiply the given number with 10 gives 64*10 = 640.
Then take the half value of the given number, and multiply with 10.
Gives (64 * 1 /2  ) * 10

= 32 * 10

= 320

Now add all the computed terms in above steps with the given number,
= 640 + 320 + 64

= 1024

Thus we got the answer 1024 as fast as possible using this ways.
