2+2(67+78)30-1 = 2 + (2*145*30) - 1
= 1 + (290*30)
= 1 + 8700
= 8701

The order of priority among the operations in solving an expression is given by BEDMAS rule.
The order of priority is
* Bracket
* Exponential
* Division
* Multiplication
* Addition
* Subtraction
Solving the above expression in that order gives the correct result.
2+2(67+78)30-1
= 2+2(145)30-1 ' First solving the bracket
= 2+2*4350-1 ' Solving one multiplication
= 2+8700-1 ' Solving the other multiplication
= 8702-1 ' Next addition
= 8701 ' At last subtraction
Thus u could solve it
Hope u got wat u wanted

8701, because 67+78 = 145, 145 x 2 x 30 = 8700, 8700 + 2 - 1 = 8701

2+2(67+78)30-1=
2+2(145)30-1=
2+2*4350-1=
2+8700-1
8702-1=8701
so the answer is 8701.
hope this helps :)

2+2(145)30 - 1
= 2+60(145) - 1
= 2+ 8700 - 1
= 8702 - 1
= 8701

2+2=4
(67+78)=145
30-1+29
4(145)29
