schoolash.blog - Can you calculate the multiplication below each within 5 seconds without using a calculator?
18 x 12
12 x 17
16 x 18
13 x 17
You do was wonder if all the above calculations can be completed each within 5 seconds.
This is not magic but we can do so by the following process:
Example -> Looking for the 18 x 12
- Total the first two digits (18) with the last digit number into two (2)
----------------------------> 18 + 2 = 2 0
- Multiply the last digit is 8 x 2 = 1 6
- Then the final result is =
2_0
__1_6
------------ +
216
How?
Does the above explanation can already be understood?
We try searching some other values such as -> 14 x16
- Total the first two digits (14) with the last digit number into two (6)
-> 14 +6 = 2 0
-Multiply the last digit ie = 4x6 = 2 4
- So the end result =
2_0
__2_4
--------- +
224
Still confused?
Take it easy.
We'll try again with the following multiplication -> 13 x 15
- Total the first two digits (13) with the last digit number into two (5)
-> 13 + 5 = 1 8
-Multiply the last digit ie = 3x5 = 1 5
- So the end result =
1_8
__1_5
---------- +
195
