Answer 1

Given:

We have to find, the value of missing number (?) is:

Solution:

We know that,

The Associative Property of Addition :

( a + b ) + c = a + ( b + c )                            ........ (1)

∴ (234 + 456) + 789 = ? + (456 + 789)      ......... (2)

Equating equations (1) and (2), we get

? = 234

∴ The value of missing number (?) = 234

Thus, (234 + 456) + 789 = "234" + (456 + 789)
