Gấp nha!!!

Answer 1

[(-24,2) + 4,525] + [11,2 + (- 3,525 ) ]

= (-24,2) + 4,525 + 11,2 + (-3,525)

= [(-24,2) + 11,2] + [4,525 + (-3,525)]

= -13 + 1

= -12

Answer 2

\(=\left[\left(-24,2\right)+11,2\right]+\left[4,525+\left(-3,525\right)\right]\)

\(=\left(-13\right)+1\)

\(=\left(-12\right)\)

Answer 3

Bạn tham khảo:

[(-24,3) + 4,525] + [11,2 + (-3,525)]

= (-24,2) + 4,525 + 11,2 + (-3,525) 

= [(-24,2) + 11,2] + [4,525 + (-3,525)]

= 13,2 + 1

= 14,2
