✔ 最佳答案
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

1(a).= +(+4) = +4

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
