No, Tyson's final expression is not equivalent to the initial expression.

<h3>Fraction addition;</h3>

According to Tyson's evaluation after collecting like terms; we have;

1/5g +(-1g) + 1(3/10g) + (-1/10) + (-1/10)

open parenthesis

1/5g - 1g + 3/10g - 1/10 - 1/10

Upon addition of like terms; we have;

(-1/2)g -1/5.

Hence, the correct expression is; (-1/2)g -1/5
