What are the strategies to calculate mental math addition?

The tricky strategies to calculate addition mentally in your head is an important part in mathematics. Year-by-year practicing will help us to learn how to use mental math tricks or techniques in an appropriate way.

**Tips:** Practice whenever you get free time in school, at work, etc.,

There are some skills, which are used to solve the questions of addition easily and conveniently. Use mental math strategies to calculate addition to sharpen your mental maths skills.

Here are some examples in which mental math addition skills are used

Problems to calculate mental math tricks for addition:

4 + 8 = 8 + 4 4 + 8 = 8 + I, I, I, I = 8, 9, 10, 11, 12 Therefore, 4 + 8 = 8 + 4 = 12 |
Instead of adding 8 to 4, 4 is added to 8 as 4 + 8 = 8 + 4. While calculating mentally, we go to count four numbers ahead. |

We know that, 5 + 17 = 17 + 5 So, 17 + (I, I, I, I, I) = 17, 18, 19, 20, 21, 22 Therefore, 5 + 17 = 17 + 5 = 22 |
Instead of adding 17 to 5, 5 is added to 17 as 5 + 17 = 17 + 5. While calculating mentally, we go to count five numbers ahead. |

8 + 5 + 3 = = 11 + 5 = 16 Therefore, 8 + 5 + 3 = 8 + 3 + 5 = 16
| Instead of adding 8 + 5 + 3 we arrange the numbers as 8 + 3 + 5 then, 8 + 3 = 11 and 11 + 5 = 16 |

70 + 40 = 110 |
Only the digits at ten’s place are added, if the numbers are the multiples of 10. Zero is placed at one’s place in the addition result. |

60 + 35 = 60 + 30 + 05 = 90 + 05 = 95 Therefore, 60 + 35 = 95 |
Numbers are split in tens and ones. Sum of tens and sum of ones are added. |

67 + 43 = (60 + 7) + (40 + 3) = 60 + 40 + 7 + 3 = 100 + 10 = 110 Numbers are split in tens and ones and then do addition. |
Sum of ones and sum of tens both are added. |

**7.** Add 39 + 53

**Solution:**

39 + 53

= 39 + 1 + 53 – 1

= 40 + 52

= 92

The above tricky strategies will help us to calculate mental math addition to sharpen the math skills to perform easily.

Exponential Form = 100 = 102, where 2 is the power of 10. Laws of exponents: a-m = 1/ am a m * an = am*n am * an = am*n (am)n = am*n am / bm = (a/b)m a0= 1 (a / b)-m = (b/a)m (-1)odd = -1 (-1)even = 1 ( am / an ) = am-n read more

Exponential Form = 100 = 10^{2, }

where 2 is the power of 10.

**Laws of exponents:**

- a
^{-m }= 1/ a^{m} - a m * a
^{n }= a^{m*n } - a
^{m}* a^{n }= a^{m*n } - (am)
^{n }= a^{m*n } - am / b
^{m }= (a/b)^{m } - a0= 1
^{ } - (a / b)
^{-m}^{ }= (b/a)^{m } - (-1)
^{odd}^{ }= -1^{ } - (-1)
^{even}^{ }= 1^{ } - ( a
^{m / }a^{n})^{ }= a^{m-n}
