1/2g+-g= ?

Is the first term 1/(2g) or (1/2)g = g/2?

+(-g) is the same as -g.
Add the two terms, whatever they are.

Since g is a common factor, you may remove it and just do the "work" as normal arithmetic:

(1/2)g + (-g) = g * (1/2 - 1)

To solve the equation 1/2g + (-g), first simplify by combining like terms.

1/2g means half of g, and (-g) means the negative of g.

To add or subtract fractions, we need a common denominator. In this case, the common denominator is 2.

So, 1/2g can be rewritten as (1*2)/(2*1) * g = 2g/2 = g/2.

Now, we can rewrite the equation as g/2 - g.

To subtract fractions, the denominators must be the same. In this case, we can rewrite g as g/1, so the denominators match.

So, the equation becomes g/2 - g/1.

To subtract fractions, we need to subtract the numerators while keeping the denominator the same.

Subtracting g/2 - g/1 gives us (g - 2g)/2 = (-g)/2.

Therefore, the simplified form of the expression 1/2g - g is -g/2.
