-731/2 - 86 =?
Is that
73 1/2 - 86?
or
731/2 - 86?
-451.5
You start with PEMDAS
P arenthesis
E xponents
M ultiplication (left to right)
D ivision (left to right)
A ddition (left to right)
S ubtraction (left to right)
Since there's no parenthesis, exponents, or multiplication in this problem. You start with D in PEMDAS which is Divison.
So -731/2 which is -365.5
Since subtraction is the only thing left in the problem. We have to do this next.
So -365.5 - 86 which is -451.5
Therefore, the answer is -451.5

Why did you change the 86 to a 85?
Sonic changed 86 to 85 2/2 so that both the numerator and denominator have a fraction.
Think of a 86 pizzas. If you divide one pizza into halves you have 85 and 2/2 pizzas.
Because 86 = 86 0/0 which 0/0 can't subtract 1/2
So if I change it to a 85 the 86 became of 2/2 which is 1 but we need it to be a 2/2 to subtract 1/2.
To find the answer to the expression -731/2 - 86, we can follow these steps:
