Evaluate 22 ⋅ 8 ÷ 2 + 2

OpenStudy (anonymous):

I keep getting the answer 8 but that isn't one of the choices

rebeccaxhawaii (rebeccaxhawaii):

multiply then add so 176 divided by 4 + 2

rebeccaxhawaii (rebeccaxhawaii):

i mean 2

OpenStudy (anonymous):

wait, its 2 to the second power not 22

rebeccaxhawaii (rebeccaxhawaii):

its 90

OpenStudy (anonymous):

so it would be 4 ⋅ 8 ÷ 2 + 2

rebeccaxhawaii (rebeccaxhawaii):

bc 22 x 8 is first then that equals 176 divide that by 2 then add 2

OpenStudy (anonymous):

no its not 22 its 2 to the second power

rebeccaxhawaii (rebeccaxhawaii):

remember P.E.M.D.A.S. parenthesis exponents multiplication division addition subtraction

OpenStudy (anonymous):

yeah, shouldn't I do the exponents first?

rebeccaxhawaii (rebeccaxhawaii):

so it would be 2 x 2 then that equals 4 then 4 x 8 giving you 32 divided by 2 which is 16 now adding 2 answer is 18

OpenStudy (anonymous):

oh. okay thank you :)

rebeccaxhawaii (rebeccaxhawaii):

well there is no parenthesis so yes in this case exponents first
