Question

1/2 + (-7/2)

Answer 1

Come on. This is easy! Just use the order of operations. :) PEMDAS. Parentheses, figure out the thing sin the parentheses first, then exponents(there are non) multiplication, division, addition, and subtraction. c: if there is none of one things, skip it. c:

Answer 2

Equation is: \[\frac{1}{2}+\frac{-7}{-2}\]
Change so they both have the same denominator
\[\frac{1*-1}{2*-1}+\frac{-7}{-2}\]
\[\frac{-1}{-2}+\frac{-7}{-2}\]
Combine common terms, then solve and simplify
\[\frac{-1-7}{-2}\]
\[\frac{-8}{-2}\]
Simplify
\[4\]

\(\dfrac{1}{2} + -\dfrac{7}{2}\)

They already have a common denominator.
