solve in the brackets first. then the rest so... 8*{[(7+4)*2]-[(11-7)*4]} <-- this is the starting equation 8*{[(11)*2]-[(4)*4]} <-- here i solved the inner most brackets which was 7+4 and 11-7 8*{[22]-[16]} <-- then i multiplied 11 by 2 to get 22 and 4 by 4 to get 16 8*{6} <-- here i subtracted 16 from 22 to get 6 48 < and then the answer which i got by multiplying 6 and 8 **note: keep BEDMAS/BODMAS in your mind. u solve the inner most brackets first and then you move outside. 48 is the answer hope it helped :)
