Question

Evaluate-
20−{3×8−5−(3−25÷5)}

Answer 1

evaluate :-

$\tt \red{20 - \{3 \times 8 - 5 - (3 - 25 \div 5) \}}$

Solution :-

$\tt \: 20 - \{3 \times 8 - 5 - (3 - 25 \div 5) \} \\ \\ \tt \pink\implies \: 20 - \{3 \times 8 - 5 - (3 - 5) \} \\ \\ \tt \pink\implies \: 20 - \{3 \times 8 - 5 - ( - 2) \} \\ \\ \tt \pink\implies \: 20 - \{3 \times 8 - 5 + 2 \} \\ \\ \tt \pink\implies \: 20 - \{24 - 5 + 2 \} \\ \\ \tt \pink\implies \: 20 - \{26 - 5 \} \\ \\ \tt \pink\implies \: 20 - 21 \\ \\ \tt \pink\implies \fbox{ - 1}$
