2[18-(5+9)÷7]<br>show how you did it
Alex777 [14]
Order of operations

PEMDAS
do parntheases
then exponents
then mutiply or divide, whichever coms first
then addd or subtract, whichever comes first

so

when doing parenthases, simplify innermost parenthsees first

so

2(18-(5+9)/7)
innermost is (5+9)=14

now we gots
2(18-(14)/7)
we can distribute or multiply the invisible -1 in front of the 14

2(18-14/7)
now divide because division comes before adition
remember that it is -14/7, not just 14/7 because the negative is part of the 14

2(18-2)

now simplify parenthasees
18-2=16
so

2(16)
multiply
32

the result is 32
