Tính giá trị của biểu thức:
a) (370 + 12) : 2 = ..................
= ..................
370 + 12 : 2 = ..................
= ..................
b) (231 – 100) x 2 = ..................
= ..................
231 – 100 x 2 = ..................
= ..................
c) 14 x 6 : 2 = ..................
= ..................
14 x (6 : 2) = ..................
= ..................
d) 900 – 200 – 100 = ..................
= ..................
900 – (200 – 100) = ..................
= ..................
100+100+200+200+300+300+400+400+500+500+600+600+700+700+800+800+900+900+?
x + 200 = 100 + 900
900 - 100 + 200 x 1 =?
13 x 4 =?
Tìm x biết
100-100+200-150+x=150+200-100+100+132
100 + 200 + 800 + 300 + 900 + 700
900=

100+ 200+ 30 +300+70+700+800+900: 9 ( tinh nhanh)
900+200+300+100=?
tính đi nhé dễ mà!
