Question

D=–37+54+(–70)+(–163)+256

Answer 1

xin lỗi mình là học sinh lớp 5

Answer 2

\(D=-37+54+\left(-70\right)+\left(-163\right)+256\)

\(D=-37+54-70-163+256\)

\(D=-\left(37+163\right)+\left(54+256\right)\)

\(D=-200+300\)

\(D=100\)

Answer 3

\(D=-37+54+\left(-70\right)+\left(-163\right)+256\)

\(D=\left[-37+\left(-163\right)\right]+\left(54+256\right)+\left(-70\right)\)

\(D=-200+310+\left(-70\right)\)

\(D=40\)
