How can mental math be used fo find this sum 32 + 24 + 16

Answer 1

72

Explanation:

First break it down:

30 plus 20 equals 50

2 plus 4 equals 6

6 plus 50 equals 56

now split 6 from 16 which is 10

now add 56 plus 10 which is 66

add the 6 to 66 and you should get 72

mental math helps us do mathematics faster instead of having to do a bunch of work on paper

Answer 2

well we know 30 and 20 equal 50. plus 2 and 4, it's 56. now let's work with the 16. 56 plus 6 is 62. adding 10 from 16, it's 72.

mental math can be used in many ways and helps us do mathematics faster.
