2-38.

Simplify each of the following expressions to find the length of the tightrope.

1. $5+2+8$

$5+2+8=15$

1. $4+9+3$

$4+9+3=16$

1. $7+3+2+(-4)$

Pay attention to the negative sign. Remember that $-4$ means $4$ backwards steps.

$7+3+2+(-4)=8$

1. $8+6+2+(-5)$

Simplify this expression like you did with part (c).
