Question

(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}

Answer 1

(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}

To simplify this problem we will use order of operations. PEMDAS which stands for Parenthesis Exponent Multiplication Division Addition Subtraction

=(−5.2)+(−3.8)–{(−1.2)–[(−0.5)+0.7]}

=(−5.2)+(−3.8)–{(−1.2)–[−0.5+0.7]}

=(−5.2)+(−3.8)–{(−1.2)–[0.2]}

=(−5.2)+(−3.8)–{(−1.2)–0.2}

=(−5.2)+(−3.8)–{−1.2–0.2}

=(−5.2)+(−3.8)–{-1.4}

=(−5.2)+(−3.8)+1.4

=(−5.2)−3.8+1.4

=(−5.2)-2.4

=−5.2-2.4

=-7.6

Hence final answer is -7.6.
