Answer 1

Answer:

42

Step-by-step explanation:

63-(-3){-2-8-3}

( 1st we will do 8-3 as it has a dash above it and use BODMAS rule)

63-(-3){-2-5}

( there a rule that, if the numbers are same we add the numbers add put the common sign and also 1st we will do the curly bracket)

63-(-3){-7}

( now we will multiply, and ans will be in - * - = +)

63-(21)

(- * + = -)

63-21=42
