The expression after simplification is -57
Given the expression 14+{−2+3[1+3(−6−2)]}
Using the PEDMAS method
P is parenthesis
E is exponent
D is division
M is multiplication
A is addition
S is subtraction
14+{−2+3[1+3(−6−2)]}
= 14+{−2+3[1+3(-8)]}
= 14+{−2+3[1+(-24)]}
= 14+{−2+3[1-24]}
= 14+{−2+3[-23]}
= 14+{−2+[-69]}
= 14+{−2-69}
= 14+(-71)
= 14 - 71
= -57
Hence the value of the expression after simplification is -57
