Dear Student.

we first perform the addition of  234251 and 352421 = 586672586672

to find the number that we need to subtract from 925564 to get  586672 we need to first subtract the two numbers, =  925564 - 586672 = 338892

Hence that number is 338892.

Subtracting 338892 from 925564 we shall get the sum of  234251 and 352421 which is 586672
