Question

a) \(56+\left(-29\right)+\left(-7\right)+28+13+\left(-35\right)\)

b) \(\left(-213\right)+186+\left(-14\right)+217+54+\left(-49\right)\)

c)\(435+\left(-43\right)+\left(-483\right)+\left(-57\right)+383+\left(-415\right)\)

Answer 1

a) \(56+\left(-29\right)+\left(-7\right)+28+13+\left(-35\right)\)

\(=27+\left(-7\right)+28+13+\left(-35\right)\)

\(=20+28+13+\left(-35\right)\)

\(=48+13+\left(-35\right)\)

\(=61+\left(-35\right)\)

\(=26\)

b) \(\left(-213\right)+186+\left(-14\right)+217+54+\left(-49\right)\)

\(=\left(-27\right)+\left(-14\right)+217+54+\left(-49\right)\)

\(=\left(-41\right)+217+54+\left(-49\right)\)

\(=176+54+\left(-49\right)\)

\(=230+\left(-49\right)\)

\(=181\)

c) \(435+\left(-43\right)+\left(-483\right)+\left(-57\right)+383+\left(-415\right)\)

\(=392+\left(-483\right)+\left(-57\right)+383+\left(-415\right)\)

\(=\left(-91\right)+\left(-57\right)+383+\left(-415\right)\)

\(=\left(-148\right)+383+\left(-415\right)\)

\(=235+\left(-415\right)\)

\(=-180\)
