By Liliana
a) |-37| + (-25) × (-4)
= |-37| + 100
= 37 + 100
= 137
b) ¹1/2 – |-3/2| + 0.25
= 3/2 – 3/2 + 1/4
= 1/4
c) |-³7/8| – 1
= 31/8 – 1
= 23/8
d) ¹1/2 ÷ 3/7 – |2/3| + |-2/5| × 5/5
= 3/2 ÷ 3/7 – 2/3 + 2/5 x 5/5
= 7/2 – 2/3 + 2/5
= 97/30
e) (-3.7) + 6,289
= 2.589
f) 4.8 × 2 – 3.728
= 9.6 – 3.728
= 5.872
g) (-3.5) × 2 – 3,728
= -10.728
vote cho mik xin 5 sao nha
