(480 x 2 - 961 + 1) + (15 x 9 + 15 x 3 - 15 - 15)
= (960 - 961 + 1) + 15 x (9 + 3 - 1 - 1)
= (960 + 1 - 961) + 15 x 10
= (961 - 961) + 150
= 0 + 150
= 150
Rất vui được giúp bạn
\(\left(480.2-961+1\right)+\left(12.9+15.3-15-15\right)\)
\(=\left(480.2-961+1\right)+\left(12.9+15.3-15.1-15.1\right)\)
\(=\left(960-961+1\right)+15.\left(9+3-1-1\right)\)
\(=\left(-1+1\right)+15.10\)
\(=0+150\)
\(=150\)
