Solve using the order of operations. (9+9+72)-4+9

PLZ ANSWER PLZ HURRY

95

Step-by-step explanation:

The order of operations is PEMDAS

Equations in PARENTHESES come first

Numbers with EXPONENTS come second

MULTIPLICATION/DIVISION problems come next (depending on which comes first in the equation

ADDITION/SUBTRACTION comes last (again, depending on which comes first in the equation)

So we do (9+9+72) first

So that equals 90

And then we subtract 4 from 90

90 - 4 = 86

Then we add 9 to 86

86 + 9 = 95
