(-163)+177+263-377=-100

ủng hộ mình tròn 650 nha

-100 

tick minh nha!!!!!

d:=145-37-55-263

=90-300

=-210

a/ \(7-20+313\)

\(=\left(-13\right)+313\)

\(=300\)

b/ \(\left(-163\right)+177-\left(377-263\right)\)

\(=\left(-163\right)+177-114\)

\(=14-114\)

\(=-100\)

c/\(\left(325-47\right)+\left(175-53\right)\)

\(=278+122\)

\(=400\)

d/\(\left(217-756\right)-\left(41-183\right)\)

\(=\left(-539\right)-\left(-142\right)\)

\(=-397\)

\(=-100\)

a/ 7 - 20 + 313

= - 13 + 313

= 300

b/ (-163) + 177 - (377 - 263)

= (-163) + 177 - 377 + 263

= [(-163) + 263] + (177 - 377)

= 100 + (-200)

= -100

c/ (325 - 47) + (175 - 53)

= 325 - 47 + 175 - 53

= (325 + 175) - (47 + 53)

= 500 - 100

= 400

d/ (217 - 756) - (41 - 183)

= 217 - 756 - 41 + 183

= (217 + 183) - ( 756 + 41)

= 400 - 797

= -397

a)\(S=\left(-11+91\right)+\left(92-12\right)+\left(93-13\right)\\ S=80+80+80=240\)

\(\)b)\(S=-111+223-123+111\\ S=\left(-111+111\right)+\left(223-123\right)\\ S=0+100=100\)

\(B=263^2+74.263+37^2\)

\(=\left(263+37\right)^2\)

\(=300^2\)

\(=90000\)

\(B=263^2+74\cdot263+37^2\)

\(=263^2+2\cdot263\cdot37+37^2\)

\(=\left(263+37\right)^2\)

\(=300^2\)

\(=90000\)
