Solve without using a number line:-

1. (-7)-8-(-23)
2. 4-(-8)+(-7)-(-8)

${\huge{\bf{\underline{\green{Solution :}}}}} </p><p>$

$1) \: ( - 7) - 8 - ( - 23) \\ →( - 7) - ( - 23) - 8 \\ → - 7 - 23 - 8 \\ → - 30 - 8 \\ → - 38$

$2) \: 4 - ( - 8) + ( - 7) - ( - 8) \\ →( - 8) + ( - 7) - ( - 8) \\ → - 8 - 7 - 8 \\ → - 23$
