Find the value of:
i. $2\ +\ 2$
ii. $( 2) \ -\ 7\ +\ ( 45\ +\ 89) \ \div \ ( 57)$

i. 

Given: $2\ +\ 2$

To find: Here we have to find the value of the given expression $2\ +\ 2$

Solution:

If we add 2 with 2 then value of 2 will increase by 2.

$2\ +\ 2\ =\ \mathbf{4}$

So, the value is 4.

ii. 

Given: $( 2) \ -\ 7\ +\ ( 45\ +\ 89) \ \div \ ( 57)$

To find: Here we have to find the value of the given expression $( 2) \ -\ 7\ +\ ( 45\ +\ 89) \ \div \ ( 57)$

Solution:

$( 2) \ -\ 7\ +\ ( 45\ +\ 89) \ \div \ ( 57)$

By BODMAS rule first solve brackets and add 45 with 89:

$=\ ( 2) \ -\ 7\ +\ ( 134) \ \div \ ( 57)$

Divide 134 by 57:

$=\ ( 2) \ -\ 7\ +\ 2.35$

Add 2 and 2.35:

$=\ 4.35\ -\ 7$

Subtract 7 from 4.35:

$=\ \mathbf{-\ 2.65}$

So, the value is $- 2.65$.
