Improve Calculation Skill in 7 Steps:
There are some easy step, by following which you can improve your calculation skills:
1. Start With Easy Calculation:
First, start with small and easy calculation like 300+550 =850, small multiplication and easy division etc. Do not start solving complicated calculation directly. Even if you know initial addition, subtraction, multiplication and division, then try to solve them quickly as much as you can.
2. Learn Tricks For Large Multiplication Or Division:
While doing large multiplication you can make use of tables or patterns, which make your calculation less time consuming and easy. Practice this pattern on table until you feel that you are perfect and can use it randomly at any time.
Some more easy tricks for division are as follows:
i) When number is divide by 2: if the last digit of the number is even number then is divide by 2.
ii) When number is divide by 4 - If the last two digits of the number is divide by 4, then the number is divisible by 4.
For example, we have 15237716 then 16 ÷ 4 = 4.
iii) When divide by 5 - If the number ends with the 5 or 0 then that number is divide by 5.
iv)When number is divide by 9 - if the sum of all the digits in the number is divisible by 9, then the number is divisible by 9.
For example, we have 183321477 is divisible by 9
=>1+8+3+3+2+1+4+7+7 = 36 and 36 ÷ 9 = 4.
Same rule is use for the number 3.
