Question

Describe how you regroup When you find the sum of 64+43

Answer 1

64 + 43 = 107
107 - 43 = 64
107 - 64 = 43

Answer 2

To regroup the sum, we need to first break them in tens and ones and then regroup them according to their place values.

Given sum:- 64+43, where 64 can be written as 60+4 and 43 can be written as 40+3, now regroup tens and ones particularly , we get

64+43

=60+4+40+3 [breaking]

=60+40+4+3 [combine according to the corresponding place values ]

=(60+40)+(4+3) [put parenthesis]

=100+7=107
