A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

4 × 32 + 16 ÷ 4 - (6 + 2)
according to pedmas first solve parenthesis in this question parenthesis part is 6+2=8
now 4*32+16/4-8
OpenStudy (shaik0124):
in pedmas we done the p part and consider the next one e which stands for expoents.since there is no exponent part we move to the next on in pedmas i.e, division
in this 4*32+16/4-8 the division part is 16/4 =4
4*32+4-8
OpenStudy (anonymous):
there is an exponent the 2 is
OpenStudy (shaik0124):
now comes the multiplication in pedmas
128+4-8

4 *32+16/4-8 division d
4*32+4-8 multiplication m
128+4-8 addition a
132-8 subtraction s

the answer is 32

then there is something wrong in ur question please recheck
