`151 xx 8 + (228 div 19)^(2)=?`

If '+' means '-' , '-' mean '+' 'xx' means ' div ' , and 'div ' means 'xx' , then the value of ( 42-12 xx 3 + 8 div 2 + 15)/(8 xx 2-4 + 9 div 3) is :

If ‘+’ means ‘-’, ‘-’ means ‘+’, ‘ xx ’ means ‘ div ’ and ‘ div ’ means ‘ xx ’ then the value of (42-12xx3+8 div 2+15)/(8xx2-4+9 div 3) is :- यदि ‘+’ का अर्थ ‘-’, ‘-’ का अर्थ ‘+’, ‘ xx ’ का अर्थ ‘ div ’ तथा ‘ div ’ का अर्थ ‘ xx ’ है, तो (42-12xx3+8 div 2+15)/(8xx2-4+9 div 3) का मान होगा :

Solve the following: 60 div 5 xx (16- 8 div 2) div 3 =?

Solve the following. {38- (60 div 5 xx bar (16-8) div 2 div 3)} = ?

The value of (0.0203xx2.92)/(0.7xx0.0365xx 2.9) div ((12.12)^2-(8.12)^2)/((0.25)^2+(0.25) (19.99)) is :- (0.0203xx2.92)/(0.7xx0.0365xx 2.9) div ((12.12)^2-(8.12)^2)/((0.25)^2+(0.25) (19.99)) का मान ज्ञात कीजिए?

(4)/(5) xx 2(3)/(4) div (5)/(8)=?

(49)^(2) xx (7)^(8) div (343)^(3) = (7)^(?)

If xx means +, + means div, - means xx and div means - , then 8xx 7 - 8 + 40 div 2 = ?
