Today in Jojo's class we went over our homework in groups. Then we asked jojo about questions we had on our homework. We went over a question that was fairly simple. We got it wrong because we didnt follow pemdas.
-25(-4/5)+ 3^3 - 32 / sqrt 4
using order of operation you do exponents first
-25(-4/5)+ 27 - 32 / sqrt4
Next we would multiply and get
20 + 27 - 32/ 2
Now this is were we got it wrong instead of following pemdas and divide we added and we got
47-32/2
15/2
we should of did
-32/2
47-16
31
This is what pemdas means:
P erenthesis
E xponents
M ultiplication
D ivide
A dding
S ubtraction
