(-52).(-56) + 52.44 = 52.56 + 52.44 = 52.(56+44) = 52.100 = 5200
(-25).(-43) - 25.53 = 25.43 - 25.53 = 25.(43-53) = 25.(-10) = -250
-56 hay --56 zậy bn?
a/5200
b/-250
tik nha các bn
a)
(-52).(-56)+52.44
=52.56+52.44
=52.(56+44)
=52.100
=5200
b)(-25).(-43)-25.53
=25.43-25.53
=25.(43-53)
=25.(-10)
=-250
(-52).(-56) + 52.44 = 52.56 + 52.44 = 52.(56+44) = 52.100 = 5200
(-25).(-43) - 25.53 = 25.43 - 25.53 = 25.(43-53) = 25.(-10) = -250

chỗ (-- 56) là 2 dấu trừ hả bn
