--聽日交-- 各位知識朋友 , 入黎幫我手 ar !!! ( 數學F.1 ) (6)

1a) (+16)÷(+4)

= 16 ÷ 4

=4

正正得正

b) (+5)÷(-5)

= 5 / -5

= -1

正負得負

c) (-9)÷(+3)

= -9 / 3

= -3

負正得負

d) (-6)÷(-6)

= -6 / -6

= 1

負負得正
e) +76∕-4

= -19

正負得負

f.+150∕+25

= 150 / 25

=6

正正得正

g ) (-6)÷(+3)

= -6 / 3

= -2

負正得負

h.(+12)÷(-1)

= 12 / -1

= -12

正負得負

1.-242∕-11

= 242 /11

= 22

負負得正

1a.(+16)÷(+4)

b.(+5)÷(-5)

c.(-9)÷(+3)

d.(-6)÷(-6)

e.+76∕-4

g.(-6)÷(+3)

h.(+12)÷(-1)

1.-242∕-11
=(+22)(- -得+)

1a.(+16)÷(+4) a.4

b.(+5)÷(-5) b.-5
c.(-9)÷(+3) c.-3
d.(-6)÷(-6) d.1
e.+76∕-4 e.-19
f.+150∕+25 f.6
g.(-6)÷(+3) g.-3
h.(+12)÷(-1) h.-12
1.-242∕-11 i.22

1(a).= +(+4) = +4
(b).= -(+5) = -5
(c).= -(+3) =- +3
(d).= -(-36) = +36
(e).= -(+19) = +19
(f). = +(+)6 = +6
(g) = -(+2) = -2
(h).= -(+12) = -12
(i).= -(-22) = +22

其實呢d數gum簡單,步驟寫黎到都可以話係多此一舉,呢d數只不過同平時一樣gum計,再加基本的負負得正(e.g.(-4)/(-2)= -(-2) = +4) ,正負得負(e.g.(+4)/(-2)= -(+2) = -4),同正正得正(e.g.(+4)/(+2)= +(+2) = +4),應該好快就記到,下次唔識一早問左同學先,就唔洸專登上黎問啦

1a .(+16)÷(+4)= 16÷4=4
b.(+5)÷(-5)= -(5÷5)= -1
c.(-9)÷(+3)= -(9÷3)= -3
d.(-6)÷(-6)=6÷6= 1
e.+76∕-4= -(76∕4)= -19
f.+150∕+25= 150/25=6
g.(-6)÷(+3)= -(6 ÷3)= -2
h.(+12)÷(-1)= -(12÷1)= -12
1.-242∕-11 = 242/11= 22

1a.(+16)÷(+4)=4
b.(+5)÷(-5)= -1
c.(-9)÷(+3)= -3
d.(-6)÷(-6)= 1
e.+76∕-4 = -19
f.+150∕+25= 6
g.(-6)÷(+3)= -2
h.(+12)÷(-1)= -12
1.-242∕-11 = 26

不知道對不對...
